Question

The structure of H2O2 in solid and gas phase crystal is given as follows:
H
BB
be
H Н
SH
Solid crystal
Gas phase
Choose the correct option(s).
(A) a'>B'
(B) a > B
(C) a >a
(D) B'>B​

Answer 1

X) is the structure of H

in the gas phase and (Y) in the solid phase.

O−O single bond length is higher in the gas phase. H−O−O bond angle is higher in the solid phase.

Hence, the correct answer is option A.
