Write the reducing agents which reduce alkyl cyanides to primary amines.

Explanation

To answer the question regarding the reducing agents that can reduce alkyl cyanides to primary amines, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Alkyl Cyanides**: Alkyl cyanides have the general formula R-C≡N, where R represents an alkyl group and C≡N is the cyanide functional group.

2. **Understand the Reduction Process**: The process of reducing alkyl cyanides involves converting the cyanide group (C≡N) into an amine group (NH2). This transformation typically requires a reducing agent.
