For a compound to be aromatic a molecule should follow hund rule
1 -conjugation in a molecule must be present
2 should be planar
3-(4n+2) pi electrons must be present
So in question 2 a molecule follow all three rulesso option d is correct
Q-3 option a is correct ....in this molecule hunds rule is not followed

For each of the species below, identify any cyclic conjugated
system, then:
1. Determine the number of electrons in a system
of cyclic conjugation (zero if no cyclic conjugation).
2. Specify whether the species is
"a"-aromatic, "aa"-anti-aromatic,
or "na"-non-aromatic (neither aromatic nor
anti-aromatic).
(Presume rings to be planar unless structure obviously prevents
planarity. If there is more than one conjugated ring, count
electrons in the largest.)
