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 diasteromers.

Answer 1

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

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

The correct statements concerning the structures E, F and G are:
(B) E, F and G are tautomers.

E is in keto form $(C=O)$ and F and G are in enol form $(C=C-OH)$

(C) F and G are geometrical isomers.

F is $Z$ isomer and E is $E$ isomer.

(D) F and G are diastereomers. They are not mirror images of each other and non-superimposable.

Options B, C, and D are correct.
