Which of the following is not formed when`N_(2)H_(4)` reacts with `H_(2)SO_(4)` to produce a series fasts?

A

`N_(2)H_(4).H_(2)SO_(4)`

B

`N_(2)H_(6)^(2+)`

C

`N_(2)H_(4)^(2+)`

D

Text Solution

Verified by Experts

The correct Answer is:
3

`N_(2)H_(4)` is weak base. It reacts with acids to form two series of salts. The salts are white ionic crystalline solids and are soluble in water.
`N_(2)H_(4)+HXrarrN_(2)H_(5)^(+)+X^(-)`
`N_(2)H_(4)+2HXrarrN_(2)H_(6)^(2+)+2X^(-)`
Solution of hydrazine is usually concentrated either by distilation or by adding `H_(2)SO_(4)` to precipitate the salt hydrazine sulphate `N_(2)H_(4).H_(2)SO_(4)`.
