Question

Two structure of $H_2{O}_2$are drawn below. Identify the phase $\left(X\right)$ and $\left(Y\right)$ of $H_2{O}_2$.

• A. $\left(X\right)$ is the structure of $H_2{O}_2$ in gas phase and $\left(Y\right)$ in solid phase
• B. $\left(X\right)$ is structure of $H_2{O}_2$ in solid phase and $\left(Y\right)$ in gas phase
• C. $\left(X\right)$ and $\left(Y\right)$ are structures of $H_2{O}_2$ in gas phase
• D. $\left(X\right)$ and $\left(Y\right)$ are structures of $H_2{O}_2$ in solid phase

Answer 1

The correct option is A $\left(X\right)$ is the structure of $H_2{O}_2$ in gas phase and $\left(Y\right)$ in solid phase

$\left(X\right)$ is the structure of $H_2{O}_2$ in the gas phase and $\left(Y\right)$ 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 $\text{A}$.
