Question

Inter molecular forces in solid hydrogen are:

• A. covalent forces
• B. van der waals forces
• C. hydrogen bond
• D. all

Answer 1

The correct option is A covalent forces

The interparticle forces in solid hydrogen are: The forces of attraction which hold an individual molecule together (for example, the covalent bonds) are known as intermolecular attractions . In hydrogens case the attractions are so weak that the molecules have to be cooled to 21 K (-252°C) before the attractions are enough to condense the hydrogen as a liquid.
conclusion: hence the option(A) is correct answer.
