Mam how to improve organic chemistry please suggest

[@rasayan_academy]

Work on basics first, spend more time reading books, practice from back questions, solve exam pyqs

Mam I have a doubt according to IR spectrum data C-H stretching frequency is greater than the C- D spectrum.But how did the bond energy of C- H become lower than that of C- D bond length

[@rasayan_academy]

In the IR, stretching frequency is inversely proportional to square root of reduced mass. Hence C-H stretching frequency is higher than C-D stretching frequency. The concept is same here, that CH bond is easier to vibrate. Hence, its zero point energy is higher than C-D, because of greater vibrations of CH than CD, even at lowest of temperatures. Thus, bond dissociation energy being approximately similar, the CH bond breaks easily due to greater vibrations. I hope it makes sense now!

@@rasayan_academyThen Mam can'nt we conclude greater the ir frequency greater wil be zero point energy and easier is to cleave the bond

Can you not talk in Hindi

[@rasayan_academy]

Actually there are multiple requests to speak in Hindi and English both, so I try to create a balance.

[@nileshsahu8399]

Ok,,but very good explanation,,,, ,,I am pursuing msc but still learn in hindi because easy to understand,,,👍
