Write structural formula for all the isomeric alcohols having the molecular formula `C_(4)H_(10)O`.

Text Solution

Verified by Experts

The correct Answer is:
4
`C_(4)H_(10)O` represents 4 isomeric alcohols:
`underset("butanol"-1)(CH_(3)CH_(2)CH_(2)OH)`, `underset("butanol"-2)(CH_(3)CH_(2)CHOHCH_(3))`
`underset(2-"methyl-propanol"-1)(CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)OH)`, `underset(2-"methylpropanol"-2)(CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)C-OH`
Further, butanol-2 shows optical isomerism, as it has one asymmetric carbon atom and exists into two optically active forms shown below:
`H-overset(C_(2)H_(5))underset(|)overset(CH_(3))overset(|)C-OH`, enantiomers
`HO - overset(CH_(3))overset(|)underset(C_(2)H_(5))underset(|)C-H`
