Current Question (ID: 10885)

Question:

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

Options:

1. $\text{Isobutyric acid}$
2. $\text{beta-Chloropropionic acid}$
3. $\text{Propionic acid}$
4. $\text{alpha-Chloropropionic acid}$ (Correct)

Solution:

$\text{Hint: If a molecule contains a chiral centre then it is optically active.}$ $\text{Step 1:}$ $\text{The structure of given compounds are as follows:}$ $\text{Isobutyric acid: } \text{H}_3\text{C}-\text{CH}(\text{CH}_3)-\text{COOH}$ $\text{beta-Chloropropionic acid: } \text{Cl}-\text{CH}_2-\text{CH}_2-\text{COOH}$ $\text{Propionic acid: } \text{H}_3\text{C}-\text{CH}_2-\text{COOH}$ $\text{alpha-Chloropropionic acid: } \text{H}_3\text{C}-\text{CH}(\text{Cl})-\text{COOH}$ $\text{(asterisk represents chiral carbon)}$ $\text{So, alpha-Chloropropionic acid is optically active because it contains an asymmetric carbon atom.}$
