What is the lowest molecular mass alkane that is chiral? Is there another alkane of the same molecular formula which is also chiral? If so, then give its structure also.

Explanation

To determine the lowest molecular mass alkane that is chiral, we need to identify an alkane with a chiral center. A chiral center is typically a carbon atom that is bonded to four different groups.

### Step-by-Step Solution:

1. **Understanding Chirality**:
- A molecule is chiral if it cannot be superimposed on its mirror image. This usually occurs when a carbon atom is attached to four different substituents.

2. **Identifying the Alkane Formula**:
