Question

Draw the resonance structures for the following compounds. Show the electron shift using curved - arrow notation:
(a) $C_{6}H_{5}OH$
(b) $C_{6}H_{5}NO_{2}$
(c) $CH_{3}CH=CHCHO$
(d) $C_{6}H_{5}-CHO$
(e) $C_{6}H_{5}-\overset{\text{+}}{C}H_{2}$
(f) $CH_{3}CH=CH\overset{\text{+}}{C}H_{2}$

Answer 1

“Resonance structures” are “two forms” of a molecule with the same chemical connectivity but electrons differently distributed around the structure. Resonance happens when “electrons” flow through adjacent pi systems.

It is a method to describe the “delocalized electrons” in certain molecules where the connection cannot be expressed explicitly by a single Lewis structure. Each Lewis structure is referred to as a contributing molecule or ion structure.
