Propan-2-ol is considered an achiral molecule. Which of the following is the primary reason for this

Q: What is the correct answer for CBSE12?

The correct answer is B. Propan-2-ol (CH₃CH(OH)CH₃) has a central carbon atom bonded to two methyl groups (CH₃), one hydrogen atom (H), and one hydroxyl group (OH). Since two of the groups attached to the central carbon are identical (the two CH₃ groups), it does not possess an asymmetric carbon atom (a carbon bonded to four different groups). Therefore, it is superimposable on its mirror image and is achiral, meaning it

Question

Propan-2-ol is considered an achiral molecule. Which of the following is the primary reason for this?

FirstInTest · Accepted Answer

Propan-2-ol (CH₃CH(OH)CH₃) has a central carbon atom bonded to two methyl groups (CH₃), one hydrogen atom (H), and one hydroxyl group (OH). Since two of the groups attached to the central carbon are identical (the two CH₃ groups), it does not possess an asymmetric carbon atom (a carbon bonded to four different groups). Therefore, it is superimposable on its mirror image and is achiral, meaning it will not rotate plane-polarized light.

Answer

It contains a carbon-carbon double bond.

Answer

It does not have an asymmetric carbon atom.

Answer

Its mirror image is non-superimposable.

Answer

It rotates plane-polarized light.
