Question

Calculate total number of optical isomers in following compound is $C{H}_3(CHOH{)}_{3}C{H}_3$

• A. $2$
• B. $4$
• C. $3$
• D. $8$

Answer 1

The correct option is B $4$

$\begin{array}{c}\\ \text{optical isomers are two compunds which}\\ \text{contain the same number and kind of}\\ \text{atoms and bonds and different spatial}\\ \text{arrangements of atoms but have non-super-}\\ \text{imposable mirror image.}\end{array}$

$\begin{array}{c}\text{Carbon(}3\text{) shows activity in (1) and (2) only .}\\ \text{it is called pseudo chiral centre.}\\ \text{so, there are}4\text{optical isomers.}\end{array}$
