Question

Draw the structural formula of an alkane that has six carbon atoms, all secondary.

Answer 1

cyclohexane.

Step-by-step explanation:

Alkanes are saturated aliphatic hydrocarbons. They form homologous series with the general molecular formula
`C_nH_(2n+2)`, where n is a whole number which is equal to or greater than 1. The first member of the series is
`CH_4` . Alkanes are tetrahedral in shape. All alkanes have similar names with the suffixes -ane. The physical properties such as melting and boiling point, density and states of matter of alkanes increases steadily with increasing molar mass. They undergo substitutional and combustion reactions;.

For secondary hydrocarbon, they exist in a ring shape or have a double functional group attached to the structure of the organic compound.

Here, an alkane with 6 carbon atoms is known as hexane but when it exists in ring shape then it is called cyclohexane.

The structure can be found in the attached file below.
