Chemistry - STEREO ISOMERISM Question with Solution | TestHub
Geometrical isomerism is a kind of stereoisomerism which is present in the compounds containing a double bond (C=C, C=N, N=N) and arise due to the restricted or frozen rotation about the double bond. The atoms or groups attached to the doubly bonded carbons must be different. In aldoximes, the isomer is named as syn if hydrogen and hydroxyl groups are on the same side of C=N bond and if these are on opposite sides, the isomer is named as anti. In ketoximes, the prefixes syn and anti indicate which group of ketoxime is syn or anti to hydroxyl group.
The geometrical isomerism is shown by :
Options:
Answer:
Solution:
Question Explanation: Identify which cyclic structure shows geometrical isomerism.
Concept:
Restricted rotation and different group attachments.
Solution:
For an exocyclic double bond, GI is shown if the carbon of the double bond has two different groups and the ring is asymmetrically substituted relative to the bond.
So, option (D) fulfills this conditions.
Final Answer: Option (D)
