Why do aldehydes and ketones have high dipole moments ?

Explanation

To understand why aldehydes and ketones have high dipole moments, we can break down the explanation into several steps:

### Step 1: Understanding Molecular Structure
Aldehydes and ketones both contain a carbonyl group (C=O). In aldehydes, the carbonyl group is located at the end of the carbon chain, while in ketones, it is found within the carbon chain.

### Step 2: Electronegativity of Oxygen
Oxygen is more electronegative than carbon. This means that oxygen attracts the shared electrons in the C=O bond more strongly than carbon does. As a result, the oxygen atom acquires a partial negative charge (δ-) while the carbon atom acquires a partial positive charge (δ+).
