Question

The correct statement(s) concerning the structures E, F and G is/are

• A. E, F and G are resonance structures
• B. E, F and E, G are tautomers
• C. F and G are geometrical isomers
• D. F and G are chain isomers

Answer 1

Answer: (B), (C)

The correct options are
B E, F and E, G are tautomers
C F and G are geometrical isomers

E, F and G are not resonance structures because there is a hydride shift between E and F

E, F and E, G are tautomers in which E is keto form and both F and G are enol form of the same E.

F and G are geometrical isomers.
