for ci) cant we just use diltute HNO3 at rtp instead of conc.HNO3 at 55 as P acts like methyl benzene and if we use conc.HNO3 at 55 wont it form tri nitro compund?

[@i.love.theamkl]

it will not form tri nitro compound as the "alkyl benzene" you mentioned is still the strong electron donating group like phenol.

[@Ferexxxx]

For b why can't we use carboxylic acid to form the amide

[@i.love.theamkl]

theoretically it works but require heating. The reason we use acyl chloride is because it more reactive and easier and faster to form amide. Acyl chloride always the best answer.
