MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

A chiral carbon atom is one that is bonded to four different atoms or groups. Let us examine each option: In the first molecule, the central carbon is bonded to two identical hydrogen (H) atoms. Thus, it is achiral. In the second molecule, the central carbon is bonded to four different groups: H, CH_3, OH, and I. Thus, it is a chiral carbon. In the third molecule, the central carbon is bonded to two identical methyl (CH_3) groups. Thus, it is achiral. In the fourth molecule, the central carbon is bonded to two identical ethyl (C_2H_5) groups. Thus, it is achiral. Therefore, only the second molecule contains a chiral carbon. Answer:
