Answer:
Step-by-step explanation:
When 2-methyl butane (also known as isopentane) is monochlorinated, the chlorine atom can substitute for the hydrogen atom at various places along the carbon chain, resulting in the generation of several isomers.
There are four distinct hydrogen atoms accessible for replacement in 2-methyl butane: one at the methyl group (C2) and three at the carbon chain (C3, C4, and C5).
Each of these hydrogen atoms can be replaced by a chlorine atom, yielding four distinct monochlorinated isomers.
As a result, the total number of isomers generated when 2-methyl butane is monochlorinated is four.
