Options

A. n-Pentane
B. Isopentane
C. n-Hexane
D. Isohexane.

Answer

C

Explanation

`C_(5)H_(12)` has mol. Wt. 72. n-pentane gives three monochloro products which are
`CH_(3)CH_(2)CH_(2)CH_(2)-CH_(2)-Cl, CH_(3)CH_(2)CH_(2)-underset(Cl)underset(|)(CH)-CH_(3)``and CH_(3)-CH_(2)-underset(Cl)underset(|)(CH)-CH_(2)-CH_(3)`
