Select the correct reaction of the following:
Correct answer: D. None of the above
- A. SnO + 4NaOH --> Sn(OH)4 + 2Na2O
- B. SnO + 4NaOH --> Na4Sn (OH)4
- C. SnO + 2NaOH --> Na2Sn (OH)4
- D. None of the above
Explanation
The correct reaction for SnO and NaOH is: SnO + 2NaOH → Na2SnO2 + H2O. In this reaction, tin(II) oxide reacts with sodium hydroxide to produce sodium stannate(II) and water. Option A is incorrect because it suggests an unbalanced reaction with incorrect products. Option B proposes a product that is not chemically feasible. Option C suggests an incorrect product formation that does not occur. Therefore, 'None of the above' is the correct choice as none of the given equations accurately represent the reaction.

About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
