Formic acid

Vedclass · Answer

(B) The boiling point of ethyl alcohol $(C_2H_5OH)$ is approximately $78 \ ^\circ C$. Formic acid $(HCOOH)$ has a higher boiling point (approximately $100.8 \ ^\circ C$) because it forms a stable dimer through intermolecular hydrogen bonding,as shown below: $H-C(=O)OH \cdots O=C(H)OH$ This extensive hydrogen bonding increases the effective molecular weight and the energy required to vaporize the substance. Propane and dimethyl ether have significantly lower boiling points than ethyl alcohol due to weaker intermolecular forces (van der Waals forces). Therefore,the boiling point of ethyl alcohol is less than that of formic acid.

The boiling point of ethyl alcohol should be less than that of:
