Q. Name the product(s) formed during the reaction of primary aliphatic amines with nitrous acid at room temperature?

Amines

Solution:

Primary aliphatic amines react with nitrous acid to form aliphatic diazonium salts which being unstable, forms alcohol and liberate nitrogen gas quantitatively .
$R- NH _{2}+ HNO _{2} \xrightarrow{ NaNO _{2}+ HCl }\left[R N _{2}^{+} Cl ^{-}\right]$
$\xrightarrow{ H _{2} O } R OH + N _{2} \uparrow+ HCl$
