Chemistry Flashcards
A,B,C
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

option:- A: 2d/v
B: d/3v
C: d/6v
equate the pressure at a point and then use P1V1=P2V2
where V1 is Al1 and V2 is Al2
the B option in enol forms a 6 membered cycle with H-bond
Find C,D
B
D
as the one becoming a aromatic system after having -ve charge is much more strong than the already aromatic system
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
