Question

Covalent compounds generally have low boiling and melting points.explain

Answer 1

As we known such covalent compounds that have relatively more flexible structures on its chain have less crystalline region（subsequent structure to crystal ）while more amorphous structure on chain to have relatively low melting point.              Hope it helps!!

Answer 2

Hey.. !! Generally ,those compounds which have low melting and boiling points have weaker bond attachment, thats why they easly break. I think same case in here
