Question 16

This question is about molecular structure, bonding, and intermolecular forces.

1.

Draw a diagram to show the strongest type of interaction between two molecules of propan-1-ol (C3H7OH\text{C}_3\text{H}_7\text{OH}C3​H7​OH) in the liquid phase. Include all lone pairs and partial charges in your diagram.

2.

Methoxyethane (CH3OCH2CH3\text{CH}_3\text{OCH}_2\text{CH}_3CH3​OCH2​CH3​) is an isomer of propan-1-ol. Table 1 shows the boiling points of propan-1-ol and methoxyethane.

Table 1

methoxyethane7

In terms of the intermolecular forces involved, explain the difference in boiling points.

3.

Draw the shape of the SO2Cl2\text{SO}_2\text{Cl}_2SO2​Cl2​ molecule and the shape of the XeF4\text{XeF}_4XeF4​ molecule. Include any lone pairs of electrons that influence the shapes.

In a SO2Cl2\text{SO}_2\text{Cl}_2SO2​Cl2​ molecule, each oxygen atom is attached to the sulfur atom by a double bond that uses two electrons from sulfur.

Name each shape.

Suggest a value for the bond angle in XeF4\text{XeF}_4XeF4​.

Name of shape of SO2Cl2\text{SO}_2\text{Cl}_2SO2​Cl2​: ______________

Name of shape of XeF4\text{XeF}_4XeF4​: ______________

Bond angle in XeF4\text{XeF}_4XeF4​: ______________
