Sort out electrophiles and nucleophiles among the following:
`CH_3 overset(+) CH_2 ,AlCl_3 ,C_2H_5 OH,CN^(-) , overset(+)CH_3 , overset(+)NO_2`,

Explanation

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

- **Electrophiles** are species that are electron-deficient and can accept electrons. They usually have a positive charge or an incomplete octet.
- **Nucleophiles** are species that are electron-rich and can donate electrons. They usually have a negative charge or lone pairs of electrons.

Now, we will analyze each of the given compounds one by one:

1. **CH₃⁺CH₂ (Carbocation)**:
