How many steroisomers are possible for `3-`chloropentan`2-ol`?

Options

A. Three
B. Two
C. Four
D. Infinite

Answer

C

Explanation

`underset(3-"Chloropentan"-2-ol)(CH_(3)CH(OH)overset(**)(CH)CICH_(3))`
The molecule of this compound contains two dissimilar chiral carbon atoms: `C - 2` and `C-3`. Thus there are four `(2^(2))` optically active stereoismers.

`M =` mirror
`I` and `II` are enantiomers, as are `III` and `IV`. The pair of `I` and `II` forms racemate`._(1)` while the pair of `III` and `IV` forms racemter`._(2)`. I and `II` are diastereomers of `III` and `IV`.
