Aromaticity of a compound can be checked by Huckel rule
according to this rule, if a compound is:-
1)planer
2) cyclic
3) conjugated
4) following (4n+2) rule then it is Aromatic if follow (4n) rule then Anti-Aromatic.
This system have 4 double bonds in conjugation and is cyclic and planer.
4 double bonds means 8 pi electrons.
Thus it follows 4n rule as 8=4×2.
and it Anti-Aromatic.
2) 2nd cyclic compound have 3 double bonds in conjugation, thus have 6 electrons.
Thus it follows 4n+2 rule.
as 4(1)+2=6 and so it is Aromatic.
can someone tell me what I did wrong please? thanks kecetakeAssignmentSessionLocator=assignment-take (References) [Review Topics) For each...
