What are the Lewis acid-base reactions (use Lewis structures)
between trimethylboron and
1. trimethyl amine (deltarHo = -74 kJ
mol-1)
2. dimethyl amine (deltarHo = -81 kJ
mol-1)
3. methyl amine (deltarHo = -74 kJ
mol-1)
4. ammonia (deltarHo = -58 kJ mol-1)
Second, prepare a graph with the standard reaction enthalpies, (deltarHo) along the y-axis and the number of methyl groups attached to the nitrogen along the x-axis. Explain the trend of deltarHo and explain possible outliers of this trend.

Label your assigned reactants in these acid-base reactions as Lewis acids (electrophiles) or Lewis bases (nucleophiles) 2. The following compound can become protonated on any of the three N atoms. However, one of the N is much more basic than the others. a. Draw the molecule with all three N protonated and then draw resonance structures for this protonated molecule. NH CH-NH-C NH b. For each resonance structure, give the formal charges on each...

1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCl stock solution. In your response to this question, be very specific about the quantities of stock solution and deionized water to be used in the dilution and the...
