Complete the following reactions:
`CH_(3)CH_(2)CH_(2)OH overset(SOCl_(2)) to? overset(alc. KOH) to? overset(HBr) to ? overset(aq. KOH) to`

Explanation

To complete the reactions step by step, we start with the given compound, which is propan-1-ol (CH₃CH₂CH₂OH).

### Step 1: Reaction with Thionyl Chloride (SOCl₂)
When propan-1-ol reacts with thionyl chloride (SOCl₂), it undergoes an SN2 reaction, where the hydroxyl group (OH) is replaced by a chlorine atom (Cl).

**Reaction:**
\[ \text{CH}_3\text{CH}_2\text{CH}_2\text{OH} + \text{SOCl}_2 \rightarrow \text{CH}_3\text{CH}_2\text{CH}_2\text{Cl} + \text{SO}_2 + \text{HCl} \]
