Structural formula is defined as the formula in which atoms are arranged in the molecule of a compound.
Alcohol: It is an organic compound having i.e. hydroxyl functional group on an aliphatic atoms of carbon.
Secondary alcohol: In this case, hydroxyl functional group is attached to carbon atom and that carbon atom is further linked with another two carbon atoms either in straight chain or cyclic form.
For example: the general structure of secondary alcohol is shown in figure (1), where R is an alkyl group.
Now, the given chemical formula is , three carbon atoms are linked with 5 hydrogen atoms and one hydroxyl functional group is attached to carbon atom.
The cyclic structural fromula of secondary alcohol is shown in figure (2).
