Statement I: The boiling points of the following hydrides of group elements increases in the order - .
Statement II: The boiling points of these hydrides increase with increase in molar mass.
In the light of the above statements, choose the most appropriate answer from the options given below:
Given below are two statements:
Statement I: The boiling points of the following hydrides of group elements increases in the order - .
Statement II: The boiling points of these hydrides increase with increase in molar mass.
In the light of the above statements, choose the most appropriate answer from the options given below:
- Correct answerABoth Statement I and Statement II are incorrect
- BStatement I is correct but Statement II is incorrect
- CStatement I is incorrect but Statement II is correct
- DBoth Statement I and Statement II are correct
Solution
Boiling point increases with molar mass of the compound, and it is also effected by hydrogen bonding.
By considering both the factors, the correct order of boiling points of 16th group hydrides is,
have the highest boiling point because of hydrogen bonding.
Hence, the correct answer is option: 'A'.
