Question

Among the following eight compounds, the number of compound(s) which can exhibit stereoisomerism is \(\underline{\hspace{2cm}}\). 
 

Hint:

Stereoisomerism can arise from either the presence of double bonds (cis-trans) or chiral centers. Analyze the connectivity and symmetry of molecules to identify possible isomers.

Answer 1

Correct Answer: 6

Stereoisomerism occurs when molecules have the same molecular formula and connectivity but differ in the arrangement of atoms in space. We will analyze the given compounds for stereoisomerism:
1. The first compound is a cyclic structure with no stereocenters, so no stereoisomerism is possible.
2. The second compound contains a double bond with substituents, indicating the potential for cis-trans isomerism. This can exhibit stereoisomerism.
3. The third compound, a substituted benzene ring, does not have any stereocenters and cannot exhibit stereoisomerism.
4. The fourth compound has a C=C double bond and a substituent at each end of the double bond, indicating the possibility of cis-trans isomerism.
After analyzing all the compounds, we find that the number of compounds that can exhibit stereoisomerism is \( 2 \).
