JAMB Chemistry 2013 Paper

Question : 38

Total: 44

Solution:

Concept:

Dehydration of the ammonium salt of an alkanoic acid produces an alkanamide.

Explanation:

The ammonium salt has the general formula

\mathrm{RCOONH_4}

On dehydration, it loses water to form an amide:

\mathrm{RCOONH_4 \rightarrow RCONH_2 + H_2O}

So the product has the general formula

\mathrm{RCONH_2}

\mathrm{C_nH_{2n+1}CONH_2}

Answer:

The option showing

\mathrm{RCONH_2}

is correct.
