Current Question (ID: 10878)

Question:

$\text{The chiral compound among the following is:}$

Options:

1. $\text{2-Methylpentanoic acid}$ (Correct)
2. $\text{Pentanoic acid}$
3. $\text{4-Methyl pentanoic acid}$
4. $\text{None of the above}$

Solution:

$\text{Hint: If molecules contain asymmetric carbon then it is chiral.}$ $\text{Explanation:}$ $\text{A carbon atom that is attached to four different types of atoms or groups of atoms is a chiral asymmetric carbon.}$ $\text{The structure of 2-methylpentanoic acid, pentanoic acid, and 4-methylpentanoic acid are as follows:}$ $\text{2-methylpentanoic acid: The carbon at position 2 (marked with *) is bonded to: -H, -CH}_3\text{, -CH}_2\text{CH}_2\text{CH}_3\text{, and -COOH}$ $\text{pentanoic acid: All carbons are bonded to at least two identical groups (no chiral center)}$ $\text{4-methylpentanoic acid: All carbons are bonded to at least two identical groups (no chiral center)}$ $\text{Only 2-methylpentanoic acid is chiral because it contains asymmetric carbon.}$
