Organic Chemistry Basics - Result Question 179
30. The correct statement(s) concerning the structures $E, F$ and $G$ is/are
$(E)$
(a) $E, F$ and $G$ are resonance forms
(b) $E, F$ and $E, G$ are isomers
(c) $F$ and $G$ are geometrical isomers
(d) $F$ and $G$ are diastereomers
Show Answer
Answer:
Correct Answer: 30. $(a, c)$
Solution:
$E, F$ and $G$ are not resonance structures because movement of hydrogen between $E$ and $F$ is involved.
$E, F$ and $E, G$ are tautomers in which $E$ is enol form and both $F$ and $G$ are keto form of the same $E$.
$F$ and $G$ are stereoisomers.
$F$ and $G$ are distereomers as they are stereo isomers but not related by mirror image relationship.
