Find the alkane (C5H12), which will give only one type of monohalogenated compound

Explanation

2,2-dimethylpropane is correct because it has a highly branched structure, which results in only one type of monohalogenated compound when a halogen (such as chlorine or bromine) is added. Due to its highly symmetric and branched nature, there's only one unique hydrogen atom that can be replaced by a halogen atom, leading to the formation of a single monohalogenated compound. The other hydrogen atoms are in identical chemical environments and thus would result in the same product.Option B, C, and D are incorrect because they do not possess the highly branched structure of 2,2-dimethylpropane, leading to the possibility of multiple monohalogenated compounds due to the presence of different types of hydrogen atoms or various positions for halogenation.
