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.
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.
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
@@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😊😊
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
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
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 🙏🙏🙏🙏
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.
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
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
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 ?
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???
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
Thanku

maam what is the reaction occuring with m-dinotrobenzene
Great explanation😍😍😍😍😍❤️❤️
For alcohol cerric ammonium nitrate if it turns red yup

Mam, By using your method of practicals, I have scored good marks in practical exam. Thanks a lot. 😁
Bro any tips for the viva? What were you asked?
@@thatgeekysilento3082 They simply asked the reactions and terminology.

Ma’am why didn’t you did 2,4DNP 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🙄
ye kisi salt ka hoga
it is liquid sample

Maam won't the sample given finish while doing test? Will we be given more if so??
Just one thing to ask the ketone sample as you stated before adding conc NaOH. Ketone sample is aqueous ketone?
Direct sample
ma'am was our chemistry external teacher .😄😄
How to make conc. NaOH ??in our lab conc . NaOH is not given
Oh is alcohol group then can naoh is used
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.)
You may do one test
But will have to write two
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
@@jokeR-ij2bm Bhai lab jal jayega 🤣🤣🤣
Mam if we add cerric Ammonium Nitrate in Ketone then red colour appear or not????
No
Teacher ji aise hone chahiye
From basic hona chahiye
Why basic medium is needed ma'am
can anyone tell if test for unsaturation(baeyer test or bromine test) is given by C=O bond?
No its not
