Q. Identify the compound, which has maximum number of no bond resonance structures

AP EAMCETAP EAMCET 2019

Solution:

More be the H-atoms associated (bonded) with the C-atom, which is bonded with the benzene ring, more will be the number of 'no bond resonance' structures shown by them.

In structure (a)

image

the $C$-atom associated with the ring has no $H$-atom.

In structure (b)

image

the $C$-atom bonded with the ring has $2 H$-atoms.

In structure (c)

image

the $C$-atom bonded with the ring has one $H$-atom.

In structure (d)

image

the $C$ - atom bonded with the ring has $3H$ - atoms
