Which of the following statements about primary amines is false ? .

Options

A. Alky1 amines are stronger bases than ammonia .
B. Alky1 amines are stronger bases than ary1 amines.
C. Alky1 amines react with nitrous aci to produce alcohols .
D. Ary1 amines react with nitrous acid to produce phenols .

Answer

D

Explanation

Aromatic primary amines react with nitrous acid at low temperatures `(273-278K)` to form diazonium salts
`ArNH_(2)+naNO_(2)+2HXoverset(Cold)rarrAr-N-=overset(+)N:X^(bar)+NaX+2H_(2)O`
Secondary aromatic amines react with nitrous acid to yield N-nitrosoamines
`ArNHR+NaNO_(2)+HXrarrAr-overset(R)overset(R)N-N =O+NaX+H_(2)O`
Tertiary aromatic amines undergo ring substitution on reaction with nitrous acid
