Question

How does a straight-chain alkane that has five carbon atoms differ from a cycloalkane that has five carbon atoms?

The straight-chain alkane has at least one double or triple bond, but the cycloalkane has only single bonds.

The straight-chain alkane has only single bonds, but the cycloalkane has at least one double or triple bond.

The straight-chain alkane has two more hydrogen atoms than the cycloalkane.

The straight-chain alkane has two fewer hydrogen atoms than the cycloalkane.

Answer 1

The answer is C.

Answer 2

A straight-chain alkane differs from a cycloalkane in such a way that the straight-chain has more hydrogen than the cycloalkane. In this case, straight-chain has two more Hydrogen atoms than the cyclic alkane. Basically, they differ in the number of hydrogen atoms attached to the carbon. Straight-chain Alkane has a formula CnH2n+2 while cyclic alkane follows CnH2n.
