Question

Which of the following is correct?
A)$S{O}_2$ is Lewis acid as well as base.
B) $S{O}_3$ is lewis acid.
C)$N_{2}O$ is a neutral oxide.
D)$O_3$, decrease the mobility of Hg(l).

• A. A,B,C,D
• B. A,C,D
• C. B,C
• D. A,B,C

Answer 1

Answer: (A)

A,B,C,D

Lewis acid is those which can accept electron pair here SO2 and SO3 both are Lewis acid due to 2 and 3 number of electrons pair respectively.

Neutral oxide neither show acidic nor basic behavior when reacting with water, NO2 is slightly soluble in water, hence it is a neutral oxide.

Reaction of Mercury liquid and ozone is 2Hg + O3=>Hg2O + O2

Hg2O is mercurous oxide so liquid converts into oxide show that mobility decrease.
