The ring-chain isomers possible with the molecular formula `C_(3)H_(6)` are _______and _______

Explanation

To solve the question regarding the ring-chain isomers possible with the molecular formula C₃H₆, we need to identify the two types of isomers that can be formed from this molecular formula.

### Step-by-Step Solution:

1. **Understanding Ring-Chain Isomers**:
- Ring-chain isomers are compounds that have the same molecular formula but differ in structure. One form is a cyclic compound (ring), and the other is an open-chain (linear) compound.

2. **Identifying the Molecular Formula**:
...
