The dihedral angle in gaseous `H_(2)O_(2)` is

(I). H_(2)O_(2) is non- linear compound (II) In H_(2)O_(2) , the hydroxyl group are not in same plane (III) The dihedral angle in H_(2)O_(2) in its vapour phase is 90^(@) (IV) H_(2)O_(2) is planer molecule. then the correct statement (s) is/are:

The dihedral angle of H_(2)O_(2) in solid phase is

The dihedral angle of H_(2)O_(2) in solid phase is

Choose total number of correct statements about H_(2)O_(2) : (a) in the pure state, H_(2)O_(2) is almost colourless (very pale blue) (b) hydrogen peroxide has non-planar structure in both gas phase and solid phase (c) 2-ethylanthraquinol react with water to give H_(2)O_(2) (d) H_(2)O_(2) is used in pollution control (e) dihedral angle of H_(2)O_(2) is larder in gas phase compared to that in solid phase

Why the bond angle in solid phase of H_(2)O_(2) is reduced when compared to as phase of H_(2)O_(2) ?

Given below are two statements : One is labelled as Assertion A and other is labelled as Reason R. Assertion A : The dihedral angles in H_2 O_2 in gaseous phase is 90.2^@ and in solid phase is 111.5^@ . Reason R : The change in dihedral angle in solid and gaseous phase is due to the difference in the intermolecular forces. Choose the most appropriate answer from the options given below for A and R.
