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

1. A \(\mathrm{R}-\mathrm{NH}_2+3 \mathrm{R}-\mathrm{X} \rightarrow\) Hofmann exhaustive alkylation
2. B \(\mathrm{R}-\mathrm{CO}-\mathrm{NH}_2+\mathrm{Br}_2+4 \mathrm{KOH} \rightarrow:\) Hofmann degradation
3. C \(\mathrm{R}-\mathrm{CO}-\mathrm{NH}_2+4[\mathrm{H}] \stackrel{\mathrm{LiA1H}_4}{\longrightarrow}:\) Mendius reduction
4. 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
