A compound with molecular formula C(7)H(...

A compound with molecular formula `C_(7)H_(16)` shows optical isomerism, the compound will be

A

`2,3-`dimethy`1`pentane

B

`2,2-`dimethy`1`phentane

C

`2-`methy`1`heptane

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(7)H_(16)` corresponds to the heneral molecular formula `(C_(n)H_(2n+2))` of alkanes. An alkane will be optically active if it acarries just one asymmetric carbon atom in its molcule. The minimum number of carbon atoms that must be present in an alkane for just one asymmetric carbon atom to have chirality is seven. Thus, there are two simplest optically active alkanes:
