I feel very happy to see you for the first time sir...though i have been following for six months... I got confident to clear my csir only after watching your videos sir....
@@experimentalchemistry6679 yes correct 😊 both will give peak at same position, so two peaks will converge into one, in the Spectra they'll look 3 positive peaks only. Very good
@@Mounika-o5x in compound A 4 carbons( 3 CH3 and 1CH ) are having odd number of hydrogens so which are appear above the line of spectra so consider them as +ve peaks Similarly only two CH2 are present Means CH2 is even no hydrogens so appear below the line so consider them as -ve peaks
I can't seen last two examples I can see only explained example then ofter directly seen the comments Soo little bit confused...any way thanks for your responding thank you
3 positive peak and 2 negative for A 5 postive and 2 negative for B Always check the chemical environment you'll find in A and B both CH3 are same so give same peak

6 positive and 2 negative for compound B
4 positive and 2 negative for compound A
A will have 4 +ve & 2 -ve peaks...
B will have 8 +ve & 2 -ve peaks..
@@Jitendra-hd8ewfor compound B, only 6 + & 2 -ve peaks in DEPT 135⁰
In compound A 4 +ve and 2 -ve
In compound B 6 +ve and 2 -ve
thank you sir 👍👍👍
Very good 👍
But check the chemical environments also, answer will be little different
It will be 3 positive and 2 negative for A
A will have 4 +ve & 2 -ve peaks...
B will have 8 +ve & 2 -ve peaks..
@@AllBoutChemistry A will have 4 +ve & 2 -ve peaks...
B will have 8 +ve & 2 -ve peaks..
Thank you SO MUCH for great explanation
For a-4positive,2negative
For b-6positive,2negative. thank you sir
In A compound postive signals is 3, negative signals is 2
Check it again, it should be 4 positive peaks in A
is it both ch3 ' s r same chemical environment..
@@experimentalchemistry6679 yes correct 😊 both will give peak at same position, so two peaks will converge into one, in the Spectra they'll look 3 positive peaks only.
Very good
Then cpd B..Is has a 5 +ve?
A for 4 positive peak and 2 negative peak,B for 5(+)and 2(-)peak
very nice
B:- total 7 peak 5 positive 2 negative
A:- total 5 peak 3 positive 2 negative
thank you very much sir
In compounds A 4 positive peck and 2 negative peck
In compounds B 6 positive peck and 2 negative peck
For A 4 positive and 2 negative signals,
For B 6 positive and 2 negative signals.
A will have 4 +ve & 2 -ve peaks...
B will have 8 +ve & 2 -ve peaks..
Plz solve questions on whole Raman spectroscopy
In compound A 3 positive n 2 negative
Thnx sir
4 positive and 2 negative peaks for compound A.
6 positive and 2 negative peaks for compound B
But how
@@Mounika-o5x in compound A 4 carbons( 3 CH3 and 1CH ) are having odd number of hydrogens so which are appear above the line of spectra so consider them as +ve peaks
Similarly only two CH2 are present
Means CH2 is even no hydrogens so appear below the line so consider them as -ve peaks

Hi sandhya...
Thank you Sir.....
In compound A 4positive and 2 negative peak and in B 2 negative 6 positive peak
Thanks sir
Conpound A give 4(+) and 2(-) peak, Compound B will give 6(+) and 2(-) peak
in first question at 144.4 carbon should be d because it directly attached to carbonyl carbon??
Compound A .positive=4,& Negative=2
Compound B positive=6 & Negative=2
For A 3positive and 2 negative
For B 5positive and 2 negative
A compound : 4 positive and 2 negative peaks
B compund : 6 positive and 2 negative peaks
A will have 4 +ve & 2 -ve peaks...
B will have 8 +ve & 2 -ve peaks..
3 positive and 2 negative for compound A
5 positive and 2 negative for compound B
a positive value shows CH3 or either CH group so in compound a positive peaks shows 4 and in compound b positive peaks shows 6 .
For B compound has 5+ve,2-ve
very good
A 4 positive peaks and for B 6positive peaks
Please solve as many inorganic questions possible from December 2018 NET
And for B compound 5 positive and 2 negative
Check it again i think it should be 6 +ve peaks in B
@@AllBoutChemistry sir check once chemical environment of terminal methyl groups
Sir please upload chemical shift value of 13c nmr
sir can you solve the 116th problem in 2014 december
A- 4positive,2 negative
B- 6 positive,2 negative peaks
Is there 3positive peaks in A because of same methyl groups???
Correct me Plzzz...
Yes,3 +ve and 2-ve peaks for A
For B 5+ve and two -ve
For compound A 4 postive and 2 negative
For compound B 6 positive and 2 negative
A will have 4 +ve & 2 -ve peaks...
B will have 8 +ve & 2 -ve peaks..
Sir ! 2018 Dec ka question no 27 and 71 ka solutions upload kar dijye na today I am anxious because exam is at hand
4 +ve nd 2 -ve for A
& 6 +ve nd 2 -ve for B
3 positive n 2 negative for A
6 positive n 2 negative for B
First m 2 negative and 4 positive....second m 2 negative and 6 positive
4 positive n 2 negative for a
6 positive n 2 negative for b
A ( 4+) ( 2-). B (6+) (2-)
4 positive &2 negative for compound A
Check the chemical environments also
A will have 4 +ve & 2 -ve peaks...
B will have 8 +ve & 2 -ve peaks..
Sir pls you explain 13C DEPT elaborately pls sir.....
a 4 positive and 2 negative
For A 4 POSITIVE 2 NEGATIVE
FOR B 6 POSITIVE 2 NEGATIVE
For A= +ve= 4; -ve=2 and for B= +ve=6 ; -ve= 2
A will have 4 +ve & 2 -ve peaks...
B will have 8 +ve & 2 -ve peaks..
Please give me answer
3 positive peak and 2 negative for A
5 postive and 2 negative for B
Always check the chemical environment you'll find in A and B both CH3 are same so give same peak
4 positive and 2 negative for A
6 positive and 2 negative forB
Very good 👍
But check the chemical environments also, answer will be little different
