Question

if covelent bond have low boiling and melting point then why dimond have heigh melting and boiling points?? I will mark best answer as brainlist pakka​

Answer 1

Explanation:

Melting and boiling either ones require separating the carbon atoms which are bonded with strong covalent bonds , equivalent to the bonds inside the molecule since graphite or diamond are molecular it gives raise to high melting and boiling points

Answer 2

$\blue{\bold{\underline{\underline{Answer:-}}}}$

Diamond is very hard due to the strong covalent bonds and rigid tetrahedral 3d arrangement. It does not conduct electricity, as there are no electrons free to move and carry charge. It has a high melting point and boiling point as much energy is needed to break the many strong covalent bonds.
