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 C are geometrical isomers 

(d) F and G are diastereomers

Answer 1

The correct option (b) E, F and E,G are tautomers 

(c) F and C are geometrical isomers 

(d) F and G are diastereomers

Explanation:

E and F possess different place of atoms, in addition to electron pair, can be isomers only and not the resonance structures. Geometrical isomers are stereoisomers but not enantiomers-called diastereomers.
