(i) Nitric oxide becomes brown when released in air. Why?(ii) BiCl3 is more stable than BiCl5. Why? |
|
Answer» (i) Nitric oxide becomes brown when released in air because Nitric oxide combines with oxygen when exposed to air to give nitrogen dioxide which is brown in colour. 2NO + O2 ⟶ 2NO2 (ii) Bi has little tendency to form pentahalides because + 5 oxidation state of Bi is much less stable than + 3 oxidation state due to inert pair effect. |
