7. Alcohol, phenol and ethers — Chemistry STD 12 Science — Question

Statement $I:$ Primary aliphatic amines react with $HNO _{2}$ to give unstable diazonium salts.

Statement $II:$ Primary aromatic amines react with $HNO _{2}$ to form diazonium salts which are stable even above $300 \,K$.

In the light of the above statements, choose the most appropriate answer from the options given below:

$NO(g) + Br_2 (g) \rightleftharpoons NOBr_2 (g)$

$NOBr_2(g)+ NO(g) \longrightarrow 2NOBr(g)$

If the second step is the rate determining step, the order of the reaction with respect to $NO(g)$ is
