MCQ
Molecules whose mirror image is non superimposable over them are known as chiral. Which of the following molecules is chiral in nature?
- ✓$2-$Bromobutane
- B$1-$Bromobutane
- C$2-$Bromopropane
- D$2-$Bromopropan$-2-ol$
✓
Answer
Correct option: A.
$2-$Bromobutane
The objects which are nonsuperimposable on their mirror images are called enantiomers. It occurs on that molecule which contains asymmetric carbon or chiral $($i.e., a carbon atom attached with four different groups$.)$ in the present case a molecule of $2- $Bromobutane $[\ce{CH_3 CH_2 C^*H (Br) CH_3}]$ is a chiral molecule because,
- It contains a chiral carbon atom marked as $(C^*).$
- Its mirror image is non$-$superimposable over them.
