Consider the structural changes that occur in the following
molecules. BH3, CH4, NH3, H2O, HF
a. according to Lewis and VSEPR theory, why doe these changed
occur?
b. what are the ideal bond angles for each structure, and which
are expected to be distorted?
AlCl3 and BCl3 are strong Lewis Acids. But, CaCl2 is not a Lewis
acid. Explain why. (Hint: Write the reactions of these substances
with H2O and explain).
Consider the chlorides SnCl2, BCl3, and SCl2. Of the compounds
SnCl2, BCl3, and SCl2, which molecules will be polar and which will
be non-polar? Sketch the molecules and show the overall dipole
moments.
The following reaction is conducted, starting with 0.60 M BF3
and 0.60 M NH3.
BF3 (aq) + NH3 (aq) ⇌ BF3NH3 (aq)
Plot the value of Q for this reaction against the concentration
of BF3NH3 on the axes provided, including adding value markers to
the axes. To do this, calculate the value of Q at the following
BF3NH3 concentrations: 0.0 M, 0.1 M, 0.2 M, 0.3 M, 0.4 M, and 0.5
M. If the value of Kc for this reaction...
