11:48 benzene doesn't shows nucleophilic substitution rxn ... Bcos it's CX bond acquire partial double bond (sp2) character .So the bond cleavage is difficult in Haloarenes...

Sir , jaruri hai ki do compounds ko ek hi trike se distinguish kar sakte hai ..jaise propanol aur phenol ko Lucas test se bhi to distinguish kar sakte hai ???

[@aryyann05]

nhi kr skte

At 23:45 can it also be distinguished by formation of diazonium salt or not??

Yaar kuch samjh nhi aara ki kia hora h kiu hora h ye sab names sr ke upar se jaare h.mujhe ye bhi nhi pata inka use kaha kren😫😩😭😭

[@ggnoob-nq2ol]

the lone pair of br is involved in resonance with the benzene ring ...thats why AGNO3 does not react with it

[@ikaranthabal857]

Sir 17:08 Mei phenol pa Br2 water 💧 test nahi laga skte kya

In general tertiary alcohol does not react to oxidation
