Current Question (ID: 10884)

Question:

$\text{The optically active compound among the following is-}$

Options:

1. $\text{Glycerine}$
2. $\text{Acetaldehyde}$
3. $\text{Glyceraldehyde}$ (Correct)
4. $\text{Acetone}$

Solution:

$\text{Hint: Compound must have asymmetric carbon.}$ $\text{Explanation:}$ $\text{Glycerol, acetaldehyde, and acetone don't have asymmetric carbon, that is why they are optically inactive. The glyceraldehyde is optically active because it contains a chiral center.}$ $\text{The structure is as follows:}$ $\text{Glyceraldehyde = 2,3-Dihydroxypropanal}$ $\text{The structure shows a carbon atom (marked with *) bonded to four different groups: -OH, -H, -CHO, and -CH}_2\text{OH, making it a chiral center.}$ $\text{Glycerine = propane-1,2,3-triol}$ $\text{In glycerine, all carbon atoms are bonded to at least two identical groups, so there is no chiral center, making it optically inactive.}$
