Question

1. According to molecular orbital theory, is the highest energy orbital that contains an electron antibonding or bonding in O22- ?

2.Of H2CO and CO and CO2, the compound having the strongest C-O bond is

3. Which of the following compounds has the highest boiling point? a. H3C-O-CH3 b.

c. CH3CH2OH

d. HOCH2CH2OH

5.When a narrow diameter glass tube is inserted into a body of water, water rises in the tube and its surface inside is concave upwards. Which statement, concerning the strength of the intermolecular forces between glass and water molecules compared to those between water molecules, is accurate?

a.The forces of attraction between the glass and water are stronger than those in water.

b.The forces of attraction between the glass and water are weaker than those in water.

c.The forces of attraction between the glass and water are the same as those in water.

d.Intermolecular forces are irrelevant to this situation.

Explanation / Answer

1- The bonding orbitals are at a lower energy than the antibonding orbitals.

2-CO has 1 triple bond - 3 pairs
CO2 has 2 double bonds - 4 pairs
CH2O has 2 single bonds and 1 double bond. -4 pairs

CO is strongest due to triplebond & 3 electronpairs

3- butane has more London dispersion force and so has the higher boiling point.

5-a.The forces of attraction between the glass and water are stronger than those in water.
