Chemistry - CHEMICAL BONDING Question with Solution | TestHub

${\mathrm{F}}_2<{\mathrm{Cl}}_2<{\mathrm{Br}}_2<{\mathrm{I}}_2$ (Bond length)

${\mathrm{F}}_2>{\mathrm{Cl}}_2>{\mathrm{Br}}_2>{\mathrm{I}}_2$ (Bond energy)

$2\mathrm{p}-2\mathrm{p}>2\mathrm{s}-2\mathrm{s}>2\mathrm{s}-2\mathrm{p}$ ( $\sigma$-bond strength)

$3\mathrm{p}-3\mathrm{p}>3\mathrm{p}-3\mathrm{d}>3\mathrm{d}-3\mathrm{d}$ ( $\pi$-bond strength)
