1.	Explain why diamond melts at a very high temperatuer even though it is composed of covalently linked carbon atoms.
Answer» Solution :In the crystal of diamond, each `sp^(3)`-hybridised C-atom is bonded to four others by SINGLE COVALENT bonds (bond length 1.54Å) and a large NUMBER of tetrahedral units are linked togetehr to form a three-dimensional giant molecule. Strong covalent bonds extent in all DIRECTIONAL. due to this compact structure involving strong bonds, diamond is very hard and has a very high melting point.
