Solution: Consider the following values for enthalpy of vaporization (kJ/mol) of several organic substances. Use intermolecular forces, including hydrogen-bonding interactions where applicable, to explain

Problem

Consider the following values for enthalpy of vaporization (kJ/mol) of several organic substances.

The acetaldehyde molecule has a central C double bonded above to O and single bonded left to CH3 and right to H. It has an enthalpy value of 30.4. The ethylene oxide molecule has a single-bonded triangle with O at the point and CH2 at the other two vertices. It has an enthalpy value of 28.5. The acetone molecule has a central C double bonded above to O and single bonded left and right to CH3. Its enthalpy value is 32.0. Cyclopropane has a single-bonded triangle with CH2 at all three vertices, and an enthalpy value of 24.7.

Use intermolecular forces, including hydrogen-bonding interactions where applicable, to explain your responses.
