X' is an optically active alkane having lowest molecular mass, Predict the structure of the major product obtained on monochlorination of 'X'.

Options

A. `CH_3-CH_2-CH_2-underset(Cl)underset(|)overset(CH_3)overset(|)C-CH_2-CH_3`
B. `CH_3-CH_2-CH_2-overset(CH_3)overset(|)(CH)-underset(Cl)underset(|)(CH)-CH_3`
C. `Cl-CH_(2) - CH_(2)- CH_(2)-overset(CH_(3))overset(|)(C)H- CH_(2) - CH_(3)`
D. `CH_(3) - CH_(2) - CH_(2)-overset(CH_(3))overset(|)(C)H -CH_(2) - CH_(2) - Cl`

Answer

A

Explanation

6-methyl- hexane is an optically active alkane having lowest molecular mass
