Question

Given below are two statements :

Statement I : The correct order in terms of bond dissociation enthalpy is ${Cl}_{2} > {Br}_{2} > F_{2} > I_{2}$ .

Statement II : The correct trend in the covalent character of the metal halides is $[{SnCl}_{4} > {SnCl}_{2}], [{PbCl}_{4} > {PbCl}_{2}] and [{UF}_{4} > {UF}_{6}] .$

In the light of the above statements, choose the correct answer from the options given below : [2026]

$Statement-I :$

$Bond energy order is {Cl}_{2} > {Br}_{2} > F_{2} > I_{2}$

$Bond energy increases with increase in bond order.$

$Statement-II :$

$Correct order of covalent character$

$According to Fajan's rule, higher the charge on cation, greater is the covalent character.$

${PbCl}_{2} < {PbCl}_{4},$

${UF}_{6} > {UF}_{4},$

${SnCl}_{4} > {SnCl}_{2}$

Solution

1 Both Statement I and Statement II are true

2 Statement I is true but Statement II is false

3 Both Statement I and Statement II are false

4 Statement I is false but Statement II is true
