Given below are two statements: Statement I: The reducing character of hydrogen halides increases in the order HF Statement II: The bond dissociation enthalpy of the H-X bond decreases from HF to HI due to an increase in the size of the halogen atom. In the light of the above statements, choose the most appropriate answer from the options given below.
Options
- ABoth Statement I and Statement II are correct.
- BBoth Statement I and Statement II are incorrect.
- CStatement I is correct but Statement II is incorrect.
- DStatement I is incorrect but Statement II is correct.
Correct answer
A. Both Statement I and Statement II are correct.
Step-by-step solution
Statement I is correct. The reducing character of hydrogen halides increases down the group in the order HF Statement II is correct. As the size of the halogen atom increases from F to I , the H-X bond length increases. Consequently, the bond dissociation enthalpy decreases from HF to HI , which makes it easier to break the bond and release hydrogen. Therefore, both Statement I and Statement II are correct. Answer: Both Statement I and Statement II are correct.
