Given below are two statements :
Statement I : Like nitrogen that can form ammonia, arsenic can form arsine.
Statement II : Antimony cannot form antimony pentoxide.

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

The correct option is: Statement I is correct but Statement II is incorrect.

Let us analyze both statements step-by-step:

Analysis of Statement I:
Nitrogen ($N$) and arsenic ($\mathrm{As}$) belong to Group 15 (nitrogen family) of the periodic table. As they belong to the same group, they share similar chemical properties and form analogous hydrides. Just as nitrogen forms ammonia (${\mathrm{NH}}_3$) by reacting with hydrogen, arsenic also reacts to form arsine (${\mathrm{AsH}}_3$). Both hydrides have a pyramidal geometry with a lone pair of electrons on the central atom. Therefore, Statement I is correct.

Analysis of Statement II:
Antimony ($\mathrm{Sb}$) is a Group 15 element. It can form oxides in both its +3 and +5 oxidation states because it has five valence electrons (${\mathrm{ns}}^2{\mathrm{np}}^3$). Antimony reacts with oxygen to form antimony pentoxide (${\mathrm{Sb}}_2{O}_5$), where antimony is in the +5 oxidation state. Therefore, the assertion that antimony cannot form antimony pentoxide is incorrect. Hence, Statement II is incorrect.

Conclusion:
Statement I is correct, but Statement II is incorrect.
