JEE Mains 2026 21st January Shift 2

Chemistry

Given below are two statements : Statement I: The correct order in terms of bond dissociation enthalpy is

\mathrm{Cl}_{2}>\mathrm{Br}_{2}>\mathrm{F}_{2}>\mathrm{I}_{2}\\

Statement II : The correct trend in the covalent character of the metal halides is

\left[\mathrm{SnCl}_{4}>\mathrm{SnCl}_{2}\right]

\left[\mathrm{PbCl}_{4}>\mathrm{PbCl}_{2}\right]

and

\left[\mathrm{UF}_{4}>\mathrm{UF}_{6}\right]\\

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

Statement I is true but Statement II is false

Both Statement I and Statement II are true

Statement I is false but Statement II is true

Both Statement I and Statement II are false

Correct Answer:

Statement-I : Bond energy order is

\mathrm{Cl}_{2}>\mathrm{Br}_{2}>\mathrm{F}_{2}>\mathrm{I}_{2}\\

Bond energy increases with increase in bond order.

\\

Statement-II Correct order of covalent character According to the Fajan's rule, higher the charge on cation, greater is the covalent character.

\\ \mathrm{PbCl}_{2}<\mathrm{PbCl}_{4}

\\ \mathrm{UF}_{6}>\mathrm{UF}_{4}

\\ \mathrm{SnCl}_{4}>\mathrm{SnCl}_{2}
