Assertion `,` Alkanes containing more than three carbone atoms exhibit chain isomerism.
Reason `:` All the `C-` atoms in alkanes are `sp^(2)-` hybridized

Note: In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. Assertion : Alkanes having more than three carbon atoms exhibit chain isomerism. Reason : All carbon atoms in alkanes are sp^3 hybridized.

Assertion : Alkeanes having more than three carbon atoms exhibit chain isomerism. Reason : All carbon atoms in alkanes are sp- hybridized

Assertion: Alkanes containing more than three carbon atoms exhibit chain isomerism. Reason: In an alkane, all carbon atoms are sp^(3) hybridised.

Assertion : Alkanes with more than three carbon atoms exhibit chain isomerism. Reason : Branching of the carbon atom chain is necessary for exhibiting chain isomerism.
