Identify substrate ' $\mathrm{A}$ ' in the following conversion.
$$
\mathrm{A}+\underset{\text { (excess) }}{\mathrm{CH}_3 \mathrm{I}} \stackrel{\Delta}{\longrightarrow} \mathrm{C}_2 \mathrm{H}_5\left(\mathrm{CH}_3\right)_3 \stackrel{+}{\mathrm{N} \mathrm{N}^{-}}
$$
- A$\mathrm{C}_2 \mathrm{H}_5 \mathrm{NO}_2$
- B$\mathrm{C}_2 \mathrm{H}_5 \mathrm{CN}$
- Correct answerC$\mathrm{C}_2 \mathrm{H}_5 \mathrm{NH}_2$
- D$\mathrm{CH}_3 \mathrm{CONH}_2$
Solution
$$
\mathrm{C}_2 \mathrm{H}_5 \mathrm{NH}_2+\underset{\text { (excess) }}{\mathrm{CH}_3 \mathrm{I}} \stackrel{\Delta}{\longrightarrow} \underset{\text { Tetraalkylammonium iodide }}{\mathrm{C}_2 \mathrm{H}_5\left(\mathrm{CH}_3\right)_3 \mathrm{NI}^{-}}
$$
The reaction is known as exhaustive alkylation of amines.
Hence, the correct answer is option: 'C'.
