Question

Question: Draw all constitutional isomers formed by monochlorination of each alkane with Cl₂ and h$v$.

Short answer

Answer

Step-by-step solution

Constitutional isomers

The organic compounds with the same molecular formula but different structural arrangements of the constituent elements are known as the constitutional isomers.

Monochlorination

The organic reaction involving the replacement of a loosely held hydrogen atom by a chlorine atom initiated by light energy is known as chlorination.

Consider the monochlorination of the given compounds,

a. In 2,2-dimethylhexane five different types of H atom are present that would give five constitutional isomers.

Monochlorination reaction

b. In n-heptane, four different H atom is present that would give rise to four constitutional isomers.

c. In methyl cyclopropane, there are four possible constitutional isomers as follows,
