Answer #1

CH3-CH2-C(H)=O

H in CHO is bonded to C and not to O.
So, this compound cant form hydrogen bonds.

For hydrogen bond to be formed, compound should have N,O or F and there should be H attached to it.

Also this compound is not an ion.
So, it cant have ion-induced dipole forces.


This compound is polar because of C=O bond.
So, there is dipole-dipole forces.

Also London-Dispersion forces are present in all molecules. Same is the case here

Answer: London dispersion forces, dipole-dipole

    Question 14 Which of the following is or are true? Molecules which have hydrogen bonded to F, 0, or N can undergo hydrogen-bonding London dispersion forces are the result of permanent dipoles in atoms or molecules. Bonding forces are much stronger than intermolecular forces. An intermolecular force is an attractive force that operates between molecules. London dispersion forces occur in all atoms and molecules.

    2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
