When acetaldehyde is heated with Fehling's solution it gives a precipitate of

Options

A. Cu
B. CuO
C. `Cu_(2)O`
D. `Cu+Cu_(2)O+CuO`

Explanation

To solve the question, "When acetaldehyde is heated with Fehling's solution, it gives a precipitate of which of the following: Cu, CuO, Cu2O, or Cu and Cu2O?", we will follow these steps:

### Step 1: Understand Fehling's Solution
Fehling's solution is a deep blue solution that contains a complex of cupric ions (Cu²⁺) and tartaric acid. It is commonly used to test for the presence of aldehydes.

### Step 2: Identify the Reactants
In this case, the reactants are acetaldehyde (CH₃CHO) and Fehling's solution (which contains Cu²⁺ ions).
