Which of the following reactions does not match correctly with its name?

• A

  $\mathrm{R}-\mathrm{NH}_2+3 \mathrm{R}-\mathrm{X} \rightarrow$ Hofmann exhaustive alkylation
• B

  $\mathrm{R}-\mathrm{CO}-\mathrm{NH}_2+\mathrm{Br}_2+4 \mathrm{KOH} \rightarrow:$ Hofmann degradation
• Correct answer
  C

  $\mathrm{R}-\mathrm{CO}-\mathrm{NH}_2+4[\mathrm{H}] \stackrel{\mathrm{LiA1H}_4}{\longrightarrow}:$ Mendius reduction
• D

  $\mathrm{R}-\mathrm{CH}_2-\stackrel{\oplus}{\mathrm{N}}-(\mathrm{R})_3 \stackrel{\oplus}{\mathrm{X}} \frac{(\mathrm{i}) \text { moist } \mathrm{Ag}_2{ }^0}{\stackrel{(\text { (ii })}{\longrightarrow},-\mathrm{H}_2{ }^0}$ : Hofmann elimination

Solution

Mendius reduction (Incorrect) By using $\mathrm{Na} / \mathrm{EtOH}$, it is known as Mendius reduction.

Hence, the correct answer is option: 'C'.
