Question

A mixture of n - Butyl amine and petrol can be separated by using:

• A. $HCl$
• B. $NaOH$
• C. $N{a}_{2}C{O}_3$
• D. $NaHC{O}_3$

Answer 1

Answer: (A)

$HCl$

n-Butyl amine is basic in nature. So when a mixture of n-Butyl amine and petrol is passed over an acid solution then n-Butyl amine will react with the acid-forming a salt and so n-Butyl amine and petrol can be separated.

So $HCl$ can be used for separation.

$NaOH$, $N{a}_{2}C{O}_3$ and $NaHC{O}_3$ are all bases.
