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 structures
(b) $E, F$ and $E, G$ are tautomers
(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 $F$ are involved.
$E, F$ 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.
$F$ and $G$ are distereomers as they are stereo isomers but not related by mirror image relationship.
