Identify the reagents shown in bold in the following equations as nucleophiles or electrophiles :
`C_6 H_5 +CH_3 overset(+ )CO to C_6 H_5 COCH_3`

Explanation

To solve the question of identifying the reagents shown in bold as nucleophiles or electrophiles, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reagents**: The equation provided is `C_6 H_5 + CH_3 + CO`. The reagent in bold is `CH_3 + CO`, which can be interpreted as a methyl cation (CH₃⁺) and a carbonyl group (C=O).

2. **Understand Electrophiles and Nucleophiles**:
- **Electrophiles**: These are species that are electron-deficient and have a positive charge or a partial positive charge. They are attracted to electron-rich species (nucleophiles).
