Question

Consider the following statements ?

(I) $ClO_{2} & NO_{2}$ both have similar tendency for dimerisation

(II) Anhydride of $HNO_{2}$ is hyponitrous acid

(III) Hydrolysis of $Mg_{3} N_{2}$ gives basic hydroxide and basic gas.

Which of the following options have only incorrect statement ?

TestHub · Accepted Answer

Statement (I) is incorrect: ClO₂ does not dimerize like NO₂ due to steric hindrance and electron repulsion.

Statement (II) is incorrect: The anhydride of HNO₂ (nitrous acid) is N₂O₃, not hyponitrous acid.

Statement (III) is correct: Hydrolysis of Mg₃N₂ yields Mg(OH)₂ (basic hydroxide) and NH₃ (basic gas).

Therefore, statements (I) and (II) are incorrect.
