Two isomers A and B having molecular formula `C_3H_8O` when passed separately over heated alumina produce compound C with molecular formula `C_3H_6`. C on ozonolysis produces D and E. Between them, D undergoes iodoform reaction but not E. Identify A, B, C, D and E. Write the equations of the reactions concerned.

Explanation

To solve the problem step by step, we need to identify the isomers A and B, the compound C formed from them, and the products D and E resulting from ozonolysis of C.

### Step 1: Identify Isomers A and B
The molecular formula given is C₃H₈O. The possible isomers for this formula include:
1. **Isomer A**: Propanol (CH₃CH₂CH₂OH) - a straight-chain alcohol (1-propanol).
2. **Isomer B**: Isopropanol (CH₃CHOHCH₃) - a branched-chain alcohol (2-propanol).

### Step 2: Reaction with Heated Alumina
