Which of the following has the smell of bitter almonds

Options

A. Nitromethane
B. Nitroethane
C. Nitrobenzene
D. Aniline

Answer

To determine which of the given compounds has the smell of bitter almonds, we can analyze each option provided:

1. **Nitromethane (CH3NO2)**: This is a simple nitro compound. It is primarily used as a solvent and in organic synthesis, but it does not have the characteristic smell of bitter almonds.

2. **Nitroethane (C2H5NO2)**: This compound is similar to nitromethane but has an ethyl group instead of a methyl group. Like nitromethane, it is used in organic synthesis and does not have the smell of bitter almonds.

3. **Nitrobenzyl (C6H5CH2NO2)**: Nitrobenzyl is a nitro compound that contains a benzyl group. This compound is known for its distinctive smell, which resembles that of bitter almonds.

4. **Aniline (C6H5NH2)**: Aniline is an aromatic amine and is used in the production of dyes and chemicals. It does not have the smell of bitter almonds.

After analyzing all the options, we can conclude that:

**The compound that has the smell of bitter almonds is Nitrobenzyl.**

### Steps:
