B. 4
C. 5
D. 7

Answer

D

Explanation

`C_(4) H_(10) O` have seven isomers are possible
`1. CH_(3) CH_(2) underset("Butan-1-ol")(CH_(2) CH_(2)) - OH`
2. `CH_(3) - underset("Butan-2-ol")(CH_(2) - underset(OH)underset(|)( C)) - CH_(3)`
3 . `CH_(3) underset("2-Methyl propan-1-ol")underset(CH_(3)) underset(|) ( C) H - CH_(2) - OH`
4 `underset("2- Methyl - propan-2-ol") (CH_(3) - overset(CH_(3))overset(|)underset(OH)underset(|)( C) - CH_(3))`
5. `underset("Methyl propyl ether")(CH_(3) - O - C_(3) H_(7))`
6. `C_(2) H_(5) underset("Diethyl ether") (-O-C_(2)) H_(5)`
