MCQ
Covalent compounds have low melting point because
- ACovalent bond is less exothermic
- BCovalent molecules have definite shape
- CCovalent bond is weaker than ionic bond
- ✓Covalent molecules are held by weak Vander Waal's force of attraction
✓
Answer
Correct option: D.
Covalent molecules are held by weak Vander Waal's force of attraction
d
The melting and the boiling points of covalent compounds are generally low because of the weak Van der Waals forces and so can be easily converted from liquid to gas or from solid to liquid.
