Textbook Question
Chapter 8, Problem 87E
The most common exceptions to the octet rule are compounds or ions with central atoms having more than eight electrons around them. PF5, SF4, CIF3, and Br3− are examples of this type of exception. Draw the Lewis structure for these compounds or ions. Which elements, when they have to, can have more than eight electrons around them? How is this rationalized?

A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.

Does this molecule contain a glycosidic bond?
If you said this molecule does contain a glycosidic bond, write the symbol
describing it.
If you said this molecule does contain a glycosidic bond, write the common
names (including anomer and enantiomer labels) of the molecules that
would be released if that bond were hydrolyzed.
If there's more than one molecule, separate each name with a comma.
