Write the intermediate steps for the following reaction.
`C_(6)H_(5)CH(OH)C-=CH overset(H_(3)O^(+))to C_(6)H_(5)CH=CHCHO`

Explanation

To break down the reaction \( C_6H_5CH(OH)C \equiv CH \overset{H_3O^+}{\rightarrow} C_6H_5CH=CHCHO \) into intermediate steps, we can follow these steps:

### Step 1: Protonation of the Alcohol
The first step involves the protonation of the hydroxyl group (-OH) by the hydronium ion (\( H_3O^+ \)). This makes the hydroxyl group a better leaving group.

**Intermediate:**
\[
C_6H_5CH(OH_2^+)C \equiv CH
