Question

The correct statements(s) concerning the structures E, F and G is (are) -

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

Answer 1

Answer: (B), (C), (D)

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

E and F; and also E and G differ in position of atom (H), so these are tautomers (not resonating structures. Geometrical isomers are also diastereomers).
