Question

The correct combination of names for isomeric alcohols with molecular formula $C_4{H}_{10}O$ is/are:

• A. $tert-\text{butanol and 2-methylpropan-2-ol}$
• B. $tert-\text{butanol and 1,1-dimethylethan-1-ol}$
• C. $n-\text{butanol and butan-1-ol}$
• D. $\text{isobutyl alcohol and 2-methylpropan-1-ol}$

Answer 1

Answer: (A), (C), (D)

The correct options are
A $tert-\text{butanol and 2-methylpropan-2-ol}$
C $n-\text{butanol and butan-1-ol}$
D $\text{isobutyl alcohol and 2-methylpropan-1-ol}$

DBU of $C_4{H}_{10}O$ is zero which indicates that these are single bonded open chain structure.
Possible structure for molecular formula $C_4{H}_{10}O$ are:
