In the gas phase, the proton affinitiesof phosphinesdecrease in the following order (CH3)3P>(CH3)2PH>CH3PH2>PH 3. Discuss the basicity in terms of steric/electronic effects. In aqueous solution, the order is reversed. Discuss what is likely responsible for the reversal in the trend.

Describe the interaction that occurs between two objects with the same electrical charge.
