organic

?

1: A
reason: pi bond is electron rich hence there will be slight repulsion in case B

1st is rit.....but is the reson rit?

2nd is rong

ya the reason is rite

1 st reason is due to aromaticity

2nd .......I go with A

in 2nd why A ....plz giv reason

A BECAUSE IT IS MORE POLAR ...... AND THE COMPOUND IS STABILISED BY RESONANCE

IN B PHENYL GROUPS TRY TO DESTABILISE THE POSITIVE CHARGE .......WILL BE LESS POLAR .................

AND HENCE DIPOLE MOMENT

in second question.

Polarise the bond C=O by C+ -- O- ... ull see that the cyclopropyl ring becomes aromatic.. hence the ionised form is more stable .. hence the dipole moment is higher as the charge is complete positive charge

just another dbt for me in second qn,

in structure A the sp 2 hybridised carbon is strained na,but we din have this in B.Though resonance structure will give us idea,but here we have two effects which superimpose each other,so which have more impact,resonance or bondangles.
