Given below are two statements: Statement I: The boiling points of the following hydrides of group 16 elements increases in the order: \( H_2O < H_2S < H_2Se < H_2Te \). 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:

  1. A
    Statement I is correct but Statement II is incorrect.
  2. B
    Statement I is incorrect but Statement II is correct.

  4. D
    Both Statement I and Statement II are incorrect.
View Answer & Solution

Correct answer · Option D

Both Statement I and Statement II are incorrect.

Explanation

Due to hydrogen bonding, \( H_2O \) has the highest boiling point among group 16 hydrides. Thus Statement I is incorrect while Statement II is generally correct for the rest.
