A compound X (having vinegar like smell) when treated with ethanol in the presence of the acid Z, gives a compound Y which has a fruity smell. The reaction is :
`C_2H_5OH + X overset(Z)to Y+H_2O`
Identify Y and Z.

Explanation

To solve the problem, we need to identify the compounds involved in the reaction described. Let's break it down step by step.

### Step 1: Identify Compound X
The question states that compound X has a vinegar-like smell. Vinegar is commonly known to be a dilute solution of acetic acid (CH₃COOH). Therefore, we can conclude that:
- **X = Acetic Acid (CH₃COOH)**

### Step 2: Identify the Acid Z
The reaction involves ethanol (C₂H₅OH) reacting with acetic acid in the presence of an acid catalyst. A common acid catalyst used in esterification reactions is sulfuric acid (H₂SO₄). Thus, we can identify:
