1-butanol has higher melting  point than diethyl ether .
1-butanol is a primary alcohol, it is capable of intermolecular hydrogen bonding because it  contains O-H bond .thus 1-butanol has a higher melting point because it can form intermolecular hydrogen bonds .
In case of diethyl ether the boiling point is less because it does not have intermolecular hydrogen bond .
Ethers are relatively inert in nature .
