delta +ve should be greater on the carbonyl C hence -I,-M should be promoting

KCN is ionic and can form K+ and CN- but AgCN has a sigma bond in them which makes it difficult to form nucleophile

we have to form a ionic compound so that it will be soluble and hence we need a acid bases reaction hence that base is selected as we already have HCl

as the one becoming a aromatic system after having -ve charge is much more strong than the already aromatic system
39
the sigma bond of C-H in the first structure is in relation to the empty P orbital of C and hence sigma--> p(empty)
anti-sigma has very high energy and hence very less possible to attain that
in the second structure the sigma bond of C-H is in relation to the double bond which has sigma pi bond and hence the answer

the 18 mm pressure is the differnece in pressure which would be Po-Pt
