B

Among the following, the conformation that corresponds to the most stable conformation of meso-butane- 2 , 3 2,3-diol is

C

Among the following, the conformation that corresponds to the most stable conformation of meso-butane- 2 , 3 2,3-diol is

D

Among the following, the conformation that corresponds to the most stable conformation of meso-butane- 2 , 3 2,3-diol is

Answer

Among the following, the conformation that corresponds to the most stable conformation of meso-butane- 2 , 3 2,3-diol is

Explanation

Solution

Meso compounds have a plane of symmetry. In case of butan-2, 3-diol, gauche form is the most stable due to intramolecular H-bonding.
The correct answer is option (B):
Among the following, the conformation that corresponds to the most stable conformation of meso-butane- 2 , 3 2,3-diol is
