Which has higher dipole moment, alkyl cyanides or alkayl isocyanides ?

Explanation

To determine which has a higher dipole moment between alkyl cyanides and alkyl isocyanides, we can follow these steps:

### Step 1: Understand the Structures
- **Alkyl Cyanide (R-C≡N)**: In this structure, the alkyl group (R) is attached to the carbon atom of the cyanide group (C≡N). The triple bond between carbon and nitrogen creates a significant dipole moment due to the electronegativity difference between carbon and nitrogen.
- **Alkyl Isocyanide (R-N≡C)**: In this structure, the alkyl group (R) is attached to the nitrogen atom of the isocyanide group (N≡C). Here, the triple bond is between nitrogen and carbon, which also creates a dipole moment.

### Step 2: Analyze Electronegativity
- The electronegativity values are:
