Question

Which of the following compounds is expected to be optically active?

• A. $(C{H}_3{)}_{2}CHCHO$
• B. $C{H}_{3}C{H}_{2}C{H}_{2}CHO$
• C. $C{H}_{3}C{H}_{2}CH\left(Br\right)CHO$
• D. $C{H}_{3}C{H}_{2}CB{r}_{2}CHO$

Answer 1

The correct option is C $C{H}_{3}C{H}_{2}CH\left(Br\right)CHO$

A compound is solid to be optically active if it does not contain plane of symmetry as well as centre of symmetry.
