[@ridashafiq1861]

Loved the explanation... God bless you💖

[@subhamoymukhopadhyay6891]

Please make a video about NMR spectroscopy (physical portion), how to solve the numerical problems coming in net exam

[@amanhashmi85]

Md shahnawaz you are good organic teacher

[@Chemistrylover]

Thank u.

[@subhamoymukhopadhyay6891]

very nice explanation.
one thing,
if possible please use large board, it will be more convenient for explainer (you) and viewer( me/us). erasing and writing (sometimes drawing) is a bit difficult to understand.
because in this type of example (pericyclic, cyclohenxane rings also) lots of thinking and layers are there.

Money problem!
This board is sponsored by one friend 😅

Thank you
