Draw one possible structure of c6h14 given that it contains one methyl group attached to a longer carbon chain.

           The Possible structures are as,

                             i) 3-Methylpentane

                            ii) 2-Methylpentane

Structures are attached below,

                  Isomerism is a phenomenon in which the molecules has same molecular formula but different structural formula. Therefore, these compounds are called as isomers of each other.

                  Isomerism is of different types, i.e.

Functional Group Isomerism:

                                             Isomers which differ in functional groups are called as functional group isomers.

Position Isomers:

                          These isomers are different due to the position of functional group.

Chain Isomers:

                       Isomers which are different in the length of parent chain.

In our case the two isomers i.e. 2- methylpentane and 3-methylpentane belong to position isomers as the position of methyl group is changing from 2 to 3 position respectively.

answer: they produce more slow than unicellular organisms.
