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 ?

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
`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)`
