When the substances Si, KCl, CH_(3)OH and C_(2)H_(6) are arranged in order of increasing melting point, what is the correct order ?

Answer»

`Si, KCl, CH_(3)OH, C_(2)H_(6)`
`CH_(3)OH,C_(2)H_(6),Si,KCl`
`KCl,Si,C_(2)H_(6),CH_(3)OH`
`C_(2)H_(6),CH_(3)OH,KCl,Si`

SOLUTION :`underset(("Molecular LATTICE"))(C_(2)H_(6)) LT underset(("Molecular lattice with H-bonding"))(CH_(3)-OH) lt underset(("Ionic lattice""))(KCl) lt underset(("Covalent lattice"))(Si)`
