Rank the following compounds in order of decreasing boiling point: potassium fluoride (KF), acetylene (C2H2), and formaldehyde (
otez555 [7]

Answer: KF > CH_2O > C_2H_2

Explanation:

The order of boiling point depends upon the type of interactions present between the molecules.

Potassium fluoride (KF) is an ionic compound and the opposite ions are held together by strong electrostatic forces.

C_2H_2 is a covalent compound and the molecules are held together by weak van der Waals' forces.

Formaldehyde is a polar compound due to presence of polar carbonyl group. Hence dipole-dipole force is present between formaldehyde molecules.

Thus the decreasing order of boiling point is:

KF > CH_2O > C_2H_2

Kisachek [45]

Answer:

Theoretical yield = 3.75g

Explanation:

Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:

Percent yield = Actual Yield / Theoretical Yield * 100

In the problem, your actual yield was 3-00g.

Percent yield is 80.0%.

Solving for theoretical yield:

80% = 3.00g / Theoretical yield * 100

Theoretical yield = 3.00g / 80.0% * 100

<h3>Theoretical yield = 3.75g</h3>
