On Pluto, where everything is frozen, astronauts discovered two forms of butane gauche and anti. Assuming that there are no rotations around single bonds, which statement about the two forms is correct ?

A

They are enantiomers

B

They are diastereoisomers

C

They are meso compounds

D

The gauche form has two stereogenic centers, and the anti has only one

Text Solution

Verified by Experts

The correct Answer is:
B

If no rotation then these two are not inter convertible and are diastereoisomer.
