Sort out electrophiles and nucleophiles among the following
`overset(+)(NO_(2)), CH_(3) overset(+)(C )H_(2), AlCl_(3), C_(2)H_(5)OH, CN^(-), overset(-)(C )H_(3)`

Explanation

To sort out the electrophiles and nucleophiles from the given list, we need to understand the definitions of both terms:

- **Electrophiles**: These are species that accept electron pairs. They are typically positively charged or electron-deficient.
- **Nucleophiles**: These are species that donate electron pairs. They are usually negatively charged or have lone pairs of electrons.

Now, let's analyze each species provided in the question:

1. **NO₂⁺ (Nitronium ion)**:
