C-CH2CHCH2-C below this -C Would this have a higher surface tension than CH2CHCH2? I thought the more branches it had the weaker the intermolecular force.
Homework Answers
Yes, you are right!
Branching in the molecules affects the intermolecular force of attraction between the molecules. That is, upon branching the surface area of the molecule decreases, consequently the intermolecular attraction decreases(Because both the quantities are proportional to each other). It can also affect the boiling point, that is, the boiling point will decrease upon branching.
But in case of corresponding molecules without branching(when chain length increases), they have a higher surface area and intermolecular force of attraction, and also have high boing point.
Therefore your first compound with branching will have a lower surface area(Not surface tension, I think you are mistaken) than CH2CH2CH2 without branching.

Surface Tension and Bubbles Surface tension is a force caused by the attraction of liquid molecules on a boundary surface for each other. It acts tangential to the surface and is modeled as a single number, the surface tension Consider a square film on a wire frame. The bottom edge is movable and, when the frame is vertical, as shown, the surface tension of the film pulls...

Why does octanol has higher bouling point than water? I belive that water can form 4 H bonds and more polar than octanol. So I expected to see higher boiling point for water. But actually, octanol has higher boiling point than water. Does it imply that octanol has stringer intermolecular force? If so, could anyone explain why?

1. In the figure below, a solution containing lung extract
exhibits hysteresis in is surface tension versus area relationship.
This means the surface tension is higher during inflation of the
lung than deflation.

Question 4 Which of the following is or are false? Surface tension of liquids increases as temperature increases. Liquids are normally about 90-95% as dense as their corresponding solid Liquids are about 1000 times denser than gases Molecules with high intermolecular forces will have high surface tension The viscosity of a liquid is a measure of its resistance to flow.
