Q12 / 90 · JEE Main 2022 (25 Jun Shift 1) · Chemistry

In the following structures, which one is having staggered conformation with maximum dihedral angle?

  • A

  • D

Solution

A staggered conformation is a chemical conformation of an ethane-like molecule in which the substituents are at the maximum distance from each other. This requires the torsional angle to be 60° .

Figure

In anti conformation the dihedral angle is 180o (maximum)

Hence, the correct answer is option: 'B'.
