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 :
- A Statement I is true but Statement II is false
- B Both Statement I and Statement II are true
- C Statement I is false but Statement II is true
- D Both Statement I and Statement II are false
Answer & Solution
Correct Answer
(A) Statement I is true but Statement II is false
Step-by-step Solution
Detailed explanation
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 the Fajan's rule, higher the charge on cation, greater is the covalent character. \(PbCl _2 UF _4\),…
