Step2247 [10]

Answer:

Draw the structures and provide the names of all the isomeric alcohols that have the molecular formula C4H10O.

Draw the structures of (a) 6-methyl-3-heptanol and (b) trans-2-methylcyclohexanol

Explanation:

Isomers are compounds with the same molecular formula but different structural arrangements of atoms.

The given molecule is:

C4H10O.

The possible isomeric alcohols structures are shown below:

Structure of (a) 6-methyl-3-heptanol:

The root word -hept indicates that the main carbon chain has seven carbons.

-ol suffix indicates the presence of alcohol functional group at third carbon.

The 6-methyl prefix indicates the presence of methyl group as the substituent at the sixth position of the main carbon chain.

The structure of 6-methyl-3-heptanol is shown below:

The structure of trans-2-methyl cyclohexanol is shown below:
