Current Question (ID: 17671)

Question:

$\text{An organic molecule necessarily shows optical activity if it:}$ $1. \text{Contains asymmetric carbon atoms}$ $2. \text{Is non-planar}$ $3. \text{Is non-superimposable on its mirror image}$ $4. \text{Is superimposable on its mirror image}$

Options:

1. $\text{Contains asymmetric carbon atoms}$
2. $\text{Is non-planar}$
3. $\text{Is non-superimposable on its mirror image}$
4. $\text{Is superimposable on its mirror image}$

Solution:

$\text{Hint: Optical activity, the ability of a substance to rotate the plane of}$ $\text{polarization of a beam of light that is passed through it.}$ $\text{Asymmetry is an essential condition for optical activity. Generally, a}$ $\text{compound containing chiral carbon is optically active.}$ $\text{The presence of chiral carbon is not a fixed condition but molecule mirror}$ $\text{image is non-superimposable then it is optically active.}$
