Which of the following is false about structure of ?
The dihedral angle in gas phase is 90.2
The dihedral angle in crystalline phase is 111.5
It has a non planar structure
both 1 and 2
As we have learnt about
It is a non-planar molecule.
The dihedral angle in the gas phase is 111.5 and in the crystalline phase, it is 90.2
Therefore, option (4) is correct.
