Organic Chemistry Basics 1 Question 23
29. The correct statement(s) about the compound
$\mathrm{H}{3} \mathrm{C}(\mathrm{HO}) \mathrm{HC}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}(\mathrm{OH}) \mathrm{CH}{3}(X)$ is/are
(a) The total number of stereoisomers possible for $X$ is 6
(b) The total number of diastereomers possible for $X$ is 3
(c) If the stereochemistry about the double bond in $X$ is trans, the number of enantiomers possible for $X$ is 4
(d) If the stereochemistry about the double bond in $X$ is cis, the number of enantiomers possible for $X$ is 2

Answer:
Correct Answer: 29. $(a, d)$
Solution:
29.
(I)
(meso)
$(\mathrm{IV}+\mathrm{V})$
(enantiomeric)
(II + III)
