`C_(2)H_(12)O` is a monohydric alcohol . How many isomers of this alcohol are possible ? How many of these contain chiral centres as well as can exhibit enantiomerism ?

Options

A. 8 and 3
B. 6 and 2
C. 4 and 2
D. 12 and 4

Answer

A

Explanation

`C_5H_12O = C_5 H_11OH`
(i) `underset("Pentan - 1-ol ")(CH_3CH_2CH_2CH_2CH_2OH)`
(ii) `underset(Pentan-2-ol(Chiral))(CH_3overset(CH_3)overset(|)CHCH_2CH_2CH_3)`
(iii) `CH_3CH_2overset(OH)overset(|)CHCH_2CH_3`
`underset("3-Methybutan-2-ol")(CH_3-overset(CH_3)overset(|)CHCH_2CH_2CH_3)`

(V) `underset("2,2-Dimethylpropan-1-ol")(CH_3-underset(CH_3)underset(|)overset(CH_3)overset(|)C-CH_3OH` (vi) `underset("2-Methylbuatan-2-ol")(CH_3-overset(CH_3)overset(|)underset(OH)underset(|)C-CH_2CH_3)`
(Vii) `underset("3-Methylbutan-2-ol(Chrial)")(CH_3-overset(CH_3)overset(|)CH-overset(OH)overset(|)CH-CH_3)`
(viii) `underset("2-Methylbutan")(CH_3CH_2overset(CH_3)overset(|)"CH"CH_2OH)`
