Number of resonating structures of the given compound are :
Options:
Answer:
C
Solution:
The ring has 6 pi electrons on 6 carbons and two adjacent-type positive carbons. Any arrangement of the two + charges is a valid structure if the other six carbons can pair into three C=C bonds.
That needs an even number of carbons between the two + atoms on each side, so the two + atoms must be an odd number of bonds apart (1 or 3).
Pairs 1 bond apart : 8. Pairs 3 bonds apart : 8. Total = 16.
