Thank u so much sir for ur valuable lecture. It's really very important topic for us. Hope u will provide us more important topics related to net , gate later on..
pie sigma pie lonepair conjaugation dominates over pie sigma pie conjugation in amides we can also apply the same on carboxylic acids and say that the freq increases as oxygen also like nitrogen has lone pairs .
Hello sir, can u explain why ester has more vibrational frequency than carboxylic acid though ester can electron donating group O-R which tend oxygen to donate it's electron compared to carboxylic acid which has O-H (COOH)
Sir please tell me the ans that if in a naturally found proline has 12C=O16 exhibits stretching freq. 1171cm-1 then what will be the stretching frequency for 13C=O18..??!!question from tifr 17 no.24
a.o.a sir i need your help.please help me in solving this one question ....co can be coordinated in carbonyls via different modes as terminal,m2 bridging and m3 bridging,give ir absorption frequency range for these and justify these ranges with at least one example?please its urgent till tomorrow morning .
what would be the vibrational frequency corresponding to the thermal energy of kT at 298k ?? a-53.47x1011 hz b 62.11 x1011hz c27.36x1011hz d 89.05x 1011hz
Awesome video Sir. There is one doubt at 21:52, Shouldn't the logic of SP2 carbon(greater the S character => greater the electronegativity and therfore C=O bond strenght increasing) be applicable to other to conjugated carbonyls also. Why this reason only for Amides?
Sir.....I have doubt in NMR.....in 1,1,2-trichloroethane, I think area ratio is 1:2 ....but in PAVIA there is 2:1...so I am confused...What is right answer??
I think ..If we look from 2 chlorine substituted then it's 1:2 & if from other side then 2:1.....actually in my university ...this topic is not started till....& I read it on my own.....that:s why I am asking..
I'm doing my M.Sc. Chemistry right now but i didn't get any teacher who can clear my concepts the way u do. sir ur concepts are so clear...how can i contact u for asking any questions??? It will be helpful for me plz reply
Jnu asks freequent questions and to get the answer 1must remember every single freequency ......i think a freequency chart should be provided .....ratta kitna marengay yarr.....being conceptul sometime u r dominated by ratafication ......sucks
