Question

Two structures of $H_{2}O_{2}$are drawn below. Identify the phases X and Y of $H_{2}O_{2}$.

• A. (X) is the structure of $H_{2}O_{2}$in gas phase and (Y) in solid phase
• B. (X) is structure of $H_{2}O_{2}$in solid phase and (Y) in gas phase
• C. (X) and (Y) are structures of $H_{2}O_{2}$in solid phase.
• D. (X) and (Y) are structures of $H_{2}O_{2}$in solid phase.

Answer 1

Answer: (A)

(X) is the structure of $H_{2}O_{2}$in gas phase and (Y) in solid phase

Answer 2

: There is a slight difference in bond lengths of O – H, O – O – and O – O – H angle in structures of $H_{2}O_{2}$in gas phase and in solid phase.
