D. 2 - chloro - 2- methylbutane

Answer

d

Explanation

The optically inactive compoun must contains achiral carbon atom (s ) . Option (d) contains achiral carbon atom `underset("2- chloropropanol")(CH_(3)-underset(H)underset(|)overset(Cl)overset(|)(C)-CHO) " " underset("2-chlorobutane (chairal)")(CH_(3)-CH_(2)-underset(H)underset(|)overset(Cl)overset(|)(C)-CH_(3))`
`underset(" ""2-chloropentane(chiral)")(CH_(3)-CH_(2)-CH_(2)-underset(H)underset(|)overset(Cl)overset(|)(C)-CH_(3)) " " underset("2-chloropentane(achairal)")(CH_(3)-CH_(2)-underset(Cl)underset(|)overset(CH_(3))overset(|)(C)-CH_(3))`
