Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

$\text{R}-\text{S}-$configuration is related to the enantiomers, which are optically active.$\left(\therefore \mathrm{\text{t}}\mathrm{\text{r}}\mathrm{\text{u}}\mathrm{\text{e}}\right)$

(ii) The mtextxing of two optically-active compounds$\left(\text{d}\mathrm{\text{a}}\mathrm{\text{n}}\mathrm{\text{d}}\text{l}-\mathrm{\text{t}}\mathrm{\text{y}}\mathrm{\text{p}}\mathrm{\text{e}}\right)$in equimolar quantity is called racemtextzation$\left(\therefore \mathrm{\text{t}}\mathrm{\text{r}}\mathrm{\text{u}}\mathrm{\text{e}}\right)$

(iii) A molecule containing plane of symmetry does not show optical$-$activity.

Hence, the given statement is false.

(iv) Optical isomers that are not enantiomers are called diastereoisomers (is true).

(v) All chiral objects are asymmetric (true)

$\therefore$A molecule containing a plane of symmetry can be optically active is the correct answer.
