Chemistry - PERIODIC TABLE Question with Solution | TestHub

Consider following order

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

(2)First electron affinity : $\mathrm{S}>\mathrm{Se}>\mathrm{Te}>\mathrm{O}$

(3)First ionisation energy: $\mathrm{B}>\mathrm{T}\ell >\mathrm{Ga}>\mathrm{Al}>\ln$

(4)Electro negativity: $\mathrm{C}>\mathrm{S}=\mathrm{Ge}=\mathrm{Sn}>\mathrm{Pb}$

(5)Acidic nature : ${\mathrm{CO}}_2>{\mathrm{SiO}}_2>{\mathrm{SeO}}_2>{\mathrm{SnO}}_2$

(6)Basic nature $\mathrm{GeO}<\mathrm{SnO}<\mathrm{PbO}$
