HW Question

Postby Brandon Gruender 3F » Sun Nov 08, 2020 11:23 pm

Select which intermolecular forces of attraction are present between CH3CHO molecules.

does anyone know what they are?

The molecule would have London dispersion forces and dipole dipole. Dispersion forces are in all molecules. Since there is an oxygen in the molecule with C and H, this makes the molecule polar, so there would be dipole dipole intermolecular forces. Hydrogen forces would not be present because the hydrogen bonds would form if O-H, F-H, or N-H bonds were present, which is not the case here because the oxygen is bonded to carbon. Hope this helps!

The answer would be London dispersion forces and dipole-dipole forces only due to the London dispersion forces always being present, and the polarity of the molecule caused by C and H which means dipole-dipole forces are present.

The answer would be London dispersion force and dipole-dipole.

London dispersion forces are always present and there would also be a dipole-dipole interaction due to the partial negative charge of the O in the OH group.
