Statement I:\(F_2O < H_2O < Cl_2O\) is the correct trend in terms of bond angle.
Statement II:\(SiF_4, SnF_4\) and \(PbF_4\) are ionic in nature. Choose the correct answer.
Given below are two statements:
Statement I:\(F_2O < H_2O < Cl_2O\) is the correct trend in terms of bond angle.
Statement II:\(SiF_4, SnF_4\) and \(PbF_4\) are ionic in nature. Choose the correct answer.
- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is true but Statement II is false
- Statement I is false but Statement II is true
The Correct Option is C
Solution and Explanation
Concept: Bond angles depend on lone pair–bond pair repulsion and electronegativity of substituents.
Step 1: {Check Statement I} Bond angles: \[ F_2O \approx 103^\circ \] \[ H_2O \approx 104.5^\circ \] \[ Cl_2O \approx 111^\circ \] Thus the correct order is: \[ F_2O < H_2O < Cl_2O \] Hence Statement I is true.
Step 2: {Check Statement II} Nature of tetrafluorides:
- \(SiF_4\): covalent
- \(SnF_4\): largely covalent
- \(PbF_4\): covalent molecular compound
Hence they are not ionic. Thus Statement II is false.
