Regarding $H_2{O}_2$ and $O_3$ the correct statements are

O–O bond order is $1.5$ in ozone which is more than the O–O bond order 1 in $H_2{O}_2.$ Ozone is endothermic substance while the formation of $H_2{O}_2$ is exothermic heat of formation of $H_2{O}_2$  liquid is $-187.78kJmo{l}^{-1}$ and that of $O_3$ is $+142.7kJmo{l}^{-1}.$  So ozone is less stable than $H_2{O}_2.$  Dipolemoment of $H_2{O}_2$ is $2.1 D$ and that of ozone is $0.53 D.$
