Given below are two statements: Statement I: The increasing order of boiling point of hydrogen halides is HCl < HBr < HI < HF. Statement II: The increasing order of melting point of hydrogen halides is HCl < HBr < HF < HI. In the light of the above statements, choose the correct answer from the options given below:

1. (1) Both Statement I and Statement II are true
2. (2) Statement I is true but Statement II is false
3. (3) Both Statement I and Statement II are false
4. (4) Statement I is false but Statement II is true

Correct answer: (1) Both Statement I and Statement II are true

Solution

Both statements accurately reflect the trends in boiling and melting points of hydrogen halides. The boiling points increase due to the strength of hydrogen bonding and molecular weight, while the melting points are influenced by molecular structure and intermolecular forces.
