Question

Compare bond lengths in butane and t butylcyclohexane

Answer 1

The lengths of the C-C bonds increases with the decrease in the resistance of said bond, for example, a triple bond has a shorter length than in the case of a single bond. Butane has the single bonds and the CC bond is hybridized with sp3 hybridization, however in the butylcyclohexane structure the CC bond is also sp3 and the angle is 120°, however the angle shown is equal to 109.5°, so there is a certain angular tension and it is very unstable with respect to butane

Step-by-step explanation:

Answer 2

The bond angles of butane and tert butylcyclohexane are different. First, butane is an alkane that has four carbon atoms and its molecular geometry is that of a straight line. While tert butylcyclohexane is a cycloalkane that forms a ring like structure with one carbon atom attached with a tert butyl branch. Second, the tert butylcyclohexane is shorter in bond length and is strained due to the branched alkyl attached to the cycloalkyl compared to the butane that has no steric hindrance.
