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
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!
Mam how to improve organic chemistry please suggest
Work on basics first, spend more time reading books, practice from back questions, solve exam pyqs

@@rasayan_academy Thank you ❤️
@@rasayan_academyThen Mam can'nt we conclude greater the ir frequency greater wil be zero point energy and easier is to cleave the bond
Then Mam can'nt we conclude greater the ir frequency greater wil be zero point energy and easier is to cleave the bond
Absolutely 👍
@@rasayan_academy Thank you ❤️❤️❤️
Kounse book se ye sab liye ho mam batao please

3000 divided by square root of 2 is not 2201.39 but 2121.32
very poor
Can you not talk in Hindi
Actually there are multiple requests to speak in Hindi and English both, so I try to create a balance.
Ok,,but very good explanation,,,,
,,I am pursuing msc but still learn in hindi because easy to understand,,,👍
