Hello sir, understood everything that you have thought, first che was very tough for me,but now its interesting and easy. A small request, pls solve all cbse problems in each and every chapter.
In phenol, Ortho and para postion are electron rich and has -ve charge...co2 can be written as o=c=o where c has postive charge...so by nucleophilic substitution...-ve attacks +ve carbon...and co2 is attached at ortho position...as it is attached oxygen gets -ve charge...and hydrogen attached there...that's how the mechanism works....so co2 is reagent Hope so it is useful
Sir u made a mistake , in 18:14 u said primary alcohol does not react with lucas reagent , but its wrong sir primary alcohol reacts with lucas reagent to give haloalkanes and water as by product , tertiary alcohol does not need anhydrous zncl2 to form haloalkanes we obtained by simply shaking, this was in haloalkanes and haloarene chapter sir !!!!!!!

Sir..phenol with sodium ...phnenyl sodium...but pheonl with NaOH thaan
. sodium phenoxate கிடைக்கும்
Sir eppadiyavadhu organic mattum finish pannunga sir please
Sir please uplode amines chapter.
