I didn't understand this well in my school.Because we have got chemistry teacher s with lack of experience.But you mam have literally explained it well.
Thank You so much mam for your guidance on chemistry practicals. It has helped me a lot, even more than my own teacher. Tomorrow is my practical exam and I need blessing for exam by touching your feet but unfortunately I cannot meet you practically. Once again thank you so much maam
U r a blessing to us students ma'am. I was fearing a lot about practicals. Though i already studied viva ques but practicals were left. Thanku so much ma'am.
@@Fithit807 dude wtf? Did I say anything wrong about her? I totally respect her and I don't think my comment is demeaning to anyone in anyways. If you feel that I have made a wrong statement, I apologise🙏.
I have no words for you mam . How easily you explain everything. Thanks mam If I got good marks in practical because of you only so once again thanks a lot mam😊😊
She is such a great human who make chemistry practical understandable other wise in lab 😊😊😅😅😅😊😊 Let me know how many have break the test tube without being caught
alcohols: -ceric amm nitrate(yellow, few drops)+ alcohols = red\orange sol ketones: ketone in basic medium first(naoh) - m-dinitrobenzene crystals(flaky, yellow) + basic ket. sol = violet - sodium nitroprusside sol + basic ket. sol = blood red
Tomorrow is my practical exam and your videos have helped a lot ma'am ❤️, So grateful for your videos, they are absolutely top class, thank you ma'am once again.
I have prelim practicals tomorrow. These videos are good for revision as this was the first practical we did in 12th so its difficult to remember from memory
Thank you so much mam. The way you even explain the reasons behind the solubility, colour change,etc. It really helps preparing for the viva side by side. My external teacher asked me the same question today, and i was able to answer because of you. Q- why is alcohol soluble in water, and why are ketones not reduced by the tollen's test.😃😇
Thank u so much mam. I am here two days before my chemistry practical exam and I am pretty much confident just and just because of u now just need ur blessings🙏🙏🙏 unfortunately can't touch ur feet but mam plz bless me 🙏🙏🙏🙏
ma'am do we have to perform both the test for ketones? For example if i perform the sodium nitroprusside test and get the blood red color, should i perform the m-dinitrobenzene test as well? Thank you for the videos nonetheless, really helpful!
For alcohol cerric ammonium nitrate if it turns red yup Fpr ketone meta di nitro benzene if it turns violet yup Or sodium nitroprosyl soln if it truns red yup
Ma'am is one test enough for testing functional group in board practicals....for example in Alcohol you did only cerric ammonium nitrate test but in my school teacher has done ester test and sodium metal test along with cerric ammonium nitrate test???
In physical apperance Hume school mein likhaya gya ki State solid hoti hai Colour white hota hai Odour odourless hota hai Aur solubility insoluble in water hota hai🙄
Hello mam . Mam our practical exams are being postponded so, it will be on 16th of Jan 2024. Mam one thing to ask that in pre-board practical I was given the organic salt not the liquid . So how will I do all the tests ?
Excuse me mam i wanna know that as in practical we will not know about the sample so do we have to perform the analysis test from alcohol even if the sample is ketone??(In front of examiner)
@@seemamakhijani721 thnks a lot mam.. I've cleared my doubts in all experiment through your videos and you're really the best teacher and I'm sure that it will help me in my practical tomorrow 😇😇
On more thing hamare teacher aap ki thrah explain bhi nahi karte....wo 1 baar mai pura theory boldete h...or chemical pakda dete h...kar naj ke liye...
maam is it compulsory to go for second conformatory test if i get my desired result in 1st test itself.(Is one confirmatory test enough or we have to write more confirmatory tests.)
For Alcohol
- Add ethanol in test tube (Alcoholic Smell)
-Add some drops of Water (No Physical change as alcohols are water soluble)
-Acidic Nature : Slightly Acidic (pH : 6 to 7)
-C.A.N Test
Add some drops of cerric ammonium nitrate in pure alcohol and you will see the colour change from colourless to Red
For Ketones
-Add some Acetone in test tube
-It would have Nail Polish Remover like smell
-Add some drops of water , If no change occurs that means ketone is soluble in water , Therefore we can conclude it must be a lower Ketone (Less Carbon)
- Nature : Slightly Acidic (pH: 6 to 7)
Test 1 :
- Add some NaOH in dil Acetone
- Add some drops of Sodium nitropruisside and you will a color change from colourless to Reddish Black
Test 2
-Add NaOH in dil Acetone
-Add crystals of m-Di Nitro Benzene
And it will change its colour from colourless to Purple Which confirms that it is ketone
Thankyou

When writing the odour for acetone, instead of writing nail polish remover, write that it has a sweet, fruity and pungent smell

For alcohol cerric ammonium nitrate if it turns red yup
Fpr ketone meta di nitro benzene if it turns violet yup
Or sodium nitroprosyl soln if it truns red yup
3:30 ketone

Cerric ammonium nitrate solution kese prepare karna hai? Use only water??

No its not

In physical apperance
Hume school mein likhaya gya ki
State solid hoti hai
Colour white hota hai
Odour odourless hota hai
Aur solubility insoluble in water hota hai🙄
ye kisi salt ka hoga
it is liquid sample
How to make conc. NaOH ??in our lab conc . NaOH is not given
Ma'am how to make cerric ammonium nitrate solution?
Ma'am please tell.
Can't we use sodium metal instead of cerric ammonium nitrate.?
No it's difficult to handle and the H2 gas liberated may catch fire.
Also the alcohol used in lab is not pure so the water present in it will react with sodium to give H2
OK madam
Thanks

Thanks a lot
Mam can you pls say why my ceric ammonium nitrate test shows yellow for methanol and not red or pink
Mam I got the ans thank you mam
Mam does ceric ammonium answer aromatic alcohol
Maam why in 2 test of ketones ,violet colour appeared above a certain layer?
ua-cam.com/video/z8KNb1qZUmc/v-deo.html
It will precipitate after some minutes
Oh is alcohol group then can naoh is used
Mam if we add cerric Ammonium Nitrate in Ketone then red colour appear or not????
No
On more thing hamare teacher aap ki thrah explain bhi nahi karte....wo 1 baar mai pura theory boldete h...or chemical pakda dete h...kar naj ke liye...
Maam won't the sample given finish while doing test? Will we be given more if so??
Mam,
Can you pls send me the reagent preparation procedure mam
Ma'am can we do the test with FeCl3?
Thankyou mam...
thank you ma'am
Just one thing to ask the ketone sample as you stated before adding conc NaOH. Ketone sample is aqueous ketone?
Direct sample
Thank you mam
It is very good
Sound should be more clear
Thank u so much mam
