How many chiral compounds are possible on monochlorination of 2-Methyl butane ?

Options

A. 8
B. 2
C. 4
D. 6

Answer

B

Explanation

2- methylbutane on monochlorination gives `4` isomers among which I and II are chiral in nature
`CH_(3) -CH_(2) _underset(CH_(3))underset(|)overset(**)CH -CH_(3)overset(C1_(2))rarr`
`CH_(3) -CH_(2)-underset(CH_(3))underset(|)overset(**) CH -CH_(3)CI+ CH_(3) - CH_(2) -underset(CH_(3))underset(|)overset(CI)overset(|)C-CH_(3)`
`+ CH_(3) -underset(**)overset(CI)overset(|)CHunderset* -CHunderset(CH_(3))underset(|) -CH_(3) +underset(C1)underset(|)CH_(2) CH_(2) - underset(CH_(3))underset(|)CH -CH_(3)`
Hence 2 chiral compounds are formed in the above reaction .
