Identify the reagents shown in bold in the following equations as nucleophiles or electrophiles :
`CH_3COCH_3 +bar(C )N to (CH_3)_2 (CN) (OH)`

Explanation

To identify the reagents in the given equation as nucleophiles or electrophiles, we will analyze the reaction step by step.

### Step 1: Understand the Terms
- **Electrophile**: An electrophile is a species that is electron-deficient and can accept an electron pair. It is typically positively charged or neutral with an electron-withdrawing group.
- **Nucleophile**: A nucleophile is a species that is electron-rich and can donate an electron pair. It is usually negatively charged or neutral with a lone pair of electrons.

### Step 2: Analyze the Given Reaction
The reaction provided is:
