The chirality of the compound:
1
2
3
4
Official Solution
Correct Option: (2)
Step 1: Chirality of a compound refers to the asymmetry in its structure that makes it non-superimposable on its mirror image. A chiral center is a carbon atom with four different substituents. Step 2: The configuration of this compound is , considering the priority of substituents and their orientation.
