Question
How many monochlorinated isomers would result from the reaction of chlorine with n-butane in the presence of UV light?
Correct Answer
Option A is the correct answer.
Detailed Explanation
n-Butane (CH3CH2CH2CH3) has two types of hydrogens: terminal (methyl) and internal (methylene). Chlorination at C1 or C4 gives 1-chlorobutane, and at C2 or C3 gives 2-chlorobutane. Thus, only 2 monochlorinated products are formed.
Hint
How many distinct types of hydrogens are in n-butane?
