Understanding the Molecular Structure
The given compound is CH3 - CH = CH - CH(OH) - Me. Here, "Me" denotes a methyl group (CH3). Analyzing the structure reveals:
- Carbon Backbone: The compound has four carbon atoms connected with a double bond and one hydroxyl (-OH) group.
- Functional Groups: The presence of the double bond and the hydroxyl group introduces stereogenic centers.
Identifying Stereogenic Centers
1. Double Bond (C2=C3):
- The double bond between C2 and C3 can exhibit cis-trans isomerism (geometric isomerism).
- For this double bond, we can have:
- Cis Isomer: Both methyl groups on the same side.
- Trans Isomer: Methyl groups on opposite sides.
2. Chiral Center (C4):
- The carbon with the hydroxyl group (C4) is a chiral center because it is bonded to four different groups (OH, CH3, CH=CH2, and H).
- This introduces an additional stereoisomer.
Calculating Total Stereoisomers
- Geometric Isomers: For the double bond, we have 2 configurations (cis and trans).
- Chiral Isomer: Each geometric isomer can be combined with the two enantiomers from the chiral center.
Thus, the total number of stereoisomers is:
- 2 (from double bond) × 2 (from chiral center) = 4 stereoisomers.
Conclusion
Therefore, the total number of stereoisomers for the compound CH3 - CH = CH - CH(OH) - Me is 4. This validates the correct answer as option 'C'.
