Given below are two statements:
Statement I: is more covalent than
Statement II: The higher oxides of halogens also tend to be more stable than the lower ones.
In the light of the above statements, choose the most appropriate answer from the options given below
Statement I: is more covalent than
Statement II: The higher oxides of halogens also tend to be more stable than the lower ones.
In the light of the above statements, choose the most appropriate answer from the options given below
- (A)Both Statement I and Statement II are correct✓ Correct
- (B)Both Statement I and Statement II are incorrect
- (C)Statement I is correct but Statement II is incorrect
- (D)Statement I is incorrect but Statement II is correct
Answer: (A)
Solution
Statement I is correct according to Fajans' rules. has higher charge and smaller size than , giving it greater polarizing power. This leads to greater polarization of the chloride ions, making more covalent than .
Statement II is also correct. Higher oxides of halogens are more stable than lower ones due to: (a) higher oxidation state stabilization, (b) greater electronegativity of the halogen allowing better accommodation of positive charge, and (c) resonance stabilization in the higher oxides.
Therefore, both statements are correct.
Statement II is also correct. Higher oxides of halogens are more stable than lower ones due to: (a) higher oxidation state stabilization, (b) greater electronegativity of the halogen allowing better accommodation of positive charge, and (c) resonance stabilization in the higher oxides.
Therefore, both statements are correct.
