How will you convert `Ph-C-=CHrarrPh-overset(O)overset(||)C-CH_(3)`?

Explanation

To convert phenylacetylene (Ph-C≡CH) into acetophenone (Ph-C(=O)-CH₃), we can follow these steps:

### Step 1: Hydration of Phenylacetylene
The first step involves the addition of water to phenylacetylene in the presence of an acid. This reaction is known as the hydration of alkynes, and it follows Markovnikov's rule.

**Reaction:**
\[ \text{Ph-C} \equiv \text{CH} + \text{H}_2\text{O} \xrightarrow{\text{H}^+} \text{Ph-CH}=\text{C(OH)-CH}_3 \]
