1.

the total number of isomeric optically active monochloro derivative of isopentane isA. twoB. threeC. fourD. one

Answer» Correct Answer - C
Isopentene `CH_(3)-CH_(2)-underset(CH_(3))underset(|)(CH)-CH_(3) overset(Cl_(2)//hv) to `
Products are (I) `CH_(3)-CH_(2)-underset(CH_(3))underset(|)(CH)-CH_(2)-Cl (s) " " (II) Cl-CH_(2)-overset(H)overset(|)underset(H)underset(|)(C)-CH_(2)CH_(3) (R)`
(III) `CH_(3)-underset(Cl)underset(|)(CH)-underset(CH_(3))underset(|)(CH)-CH_(3) (s) " " (IV) CH_(3)-underset(CH_(3))underset(|)(CH)-underset(Cl)underset(|)(C)HCH_(3) (R)`
Only (1) and (3) are optically active.
