How many pairs of chain isomers are possible for `C_4H_(16)Cl`?

Options

A. 4
B. 3
C. 2
D. 1

Answer

C

Explanation

Only two skeletons are possible for four carbon atoms.

`underset((I))(C-C-C-CtoC-C-C-overset(1)(C)-Cl)` and `underset((II))(C-overset(Cl)overset(|)(C)-C-C)`
`underset((III))(C-underset(C)underset(|)(C)-CtoC-underset(C)underset(|)(C)-overset(1)(C)-Cl)` and `underset((IV))(C-underset(C)underset(|)overset(C^(1))overset(|)(C^(2))-C)` (I) and (III) are chain isomers (II) and (IV) are chain isomers.
