(1) Butan-1-ol has higher boiling point than diethyl ether because Butan-1-ol has strong intermollecular hydrogen bonding but in diethylether they are associated with weak dipole-dipole attractions.

(2) Mechanism of 

2CH_3CH_2OH\xrightarrow[413K]{H^+}CH_3CH_2OCH_2CH_3

Step 1: Protonation

Step 2: Nucleophillic attack
