Number of C-atoms over which the + charge is delocalised in the resonance hybrid of the cation below.
Options:
Answer:
B
Solution:
Move the + charge only through C=C bonds next to it (+ ... C=C becomes C=C ... +).
Starting with the CH⁺ carbon the charge reaches 5 more carbon atoms through the alternating double bonds, so it is spread over 6 carbon atoms.
