Identify whether each of these hydrocarbons is saturated or unsaturated. Place an "S" for "saturated" next to each hydrocarbon letter that is saturated. Place a "U" for "unsaturated" next to each hydrocarbon letter that is unsaturated.

A. 2 central carbons, with C H 3 at each end, and also single bonded to the first carbon. B. 3 central carbons, with the first 2 double bonded to each other. The left end is bonded to C H 3, and the right end is bonded to 3 C H 3.C. 2 central carbons, with H above, below, and to both sides. D. 5 central carbons, with H above and below each, and H and to both ends of the chain.
ANWSERS:
A. ⇒ S
B. ⇒ U
C. ⇒ S
D. ⇒ S

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
