Question

Why does ethyl chloride (C2H5Cl) have lower boiling point than ethyl alcohol (C2H5OH) in spite of higher
molecular weight? ​

Answer 1

Though ethyl alcohol and dimethyl ether have the same molecular weight but in ethyl alcohol the hydrogen of the O−H group forms intermolecular hydrogen bonding with the OH group in another molecule. But in case of ether the hydrogen is linked to C and it is not so electronegative to encourage the hydrogen to form hydrogen bonding. Due to intermolecular H−bonding, ethyl alcohol remains in the associated form and therefore, boils at a higher temperature compared to dimethyl ether . please mark brainliest .
