It has to be 2° amine because on reaction with benzene sulphonylchloride it gives water in soluble product. As it is formed by ammonolysis of ethylchloride, so it has to be R-NH-Et type. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/cb96f6e19473a5d436f34d282f5633e9-.png" />

Q. An amine on reaction with benzenesulphonyl chloride produces a compound insoluble in alkaline solution. This amine can be prepared by ammonolysis of ethyl chloride. The correct structure of amine is :

$C H_{3} C H_{2} N H_{2}$

$C H_{3} C H_{2} C H_{2} N H C H_{3}$

$C H_{3} C H_{2} C H_{2} N H - C H_{2} C H_{3}$

It has to be $2^{\circ}$ amine because on reaction with benzene sulphonylchloride it gives water in soluble product. As it is formed by ammonolysis of ethylchloride, so it has to be $R - N H - Et$ type.

Q. An amine on reaction with benzenesulphonyl chloride produces a compound insoluble in alkaline solution. This amine can be prepared by ammonolysis of ethyl chloride. The correct structure of amine is :

CH3​CH2​NH2​

CH3​CH2​CH2​NHCH3​

CH3​CH2​CH2​NH−CH2​CH3​

It has to be 2∘ amine because on reaction with benzene sulphonylchloride it gives water in soluble product. As it is formed by ammonolysis of ethylchloride, so it has to be R−NH−Et type.

$C H_{3} C H_{2} N H_{2}$

$C H_{3} C H_{2} C H_{2} N H C H_{3}$

$C H_{3} C H_{2} C H_{2} N H - C H_{2} C H_{3}$

It has to be $2^{\circ}$ amine because on reaction with benzene sulphonylchloride it gives water in soluble product. As it is formed by ammonolysis of ethylchloride, so it has to be $R - N H - Et$ type.
