Homework Answers
Answer:-
The weakest base is the one which have delocalization of lone pair as it will not donate the electrons readily.
So the correct answer is given as follows,
D
because it have more resonating structure and lowest energy.

2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
