stepladder [879]

Answer:

4. Option C. Pentane.

5. Option D.

Explanation:

4. Hydrocarbons are compound containing carbon and hydrogen only. Hydrocarbons are said to be saturated when they contain only carbon to carbon single bond. All alkanes are saturated hydrocarbon.

The correct answer is pentane.

5. Isomerism is the phenomenon whereby two or more compounds have the same molecular formula but different structural patterns. The compounds involved are called isomers.

A careful observation of the diagram above shows that only option D satisfied the definition of Isomerism as the two compound both have the same molecular formula as C3H8O but different structural patterns.

Note: option C does not contain isomers as Isomerism can not occur in a compound having just 1 carbon atom.
