Portage Learning Chem 210 - Module 2 Problem Set
Question 1
pts

What is the shape of water?




Bent. The bond angle is 104.5 degrees.



Question 2
pts

What is autoionization, and how is it important for water?




Autoionization is the ability of a compound to react with itself to form
ions. One water molecule reacts with a second molecule to form two
ions: H3O+ and OH-. These ions exist in small amounts in pure water and
influence the chemistry of water.



Question 3
pts

Name the three non-covalent forces discussed in this module.


1. Dipole-dipole forces, 2. Hydrogen bonding, and 3. London dispersion
forces

, What type of non-covalent interaction is known as the strongest dipole-dipole
force?




hydrogen bonds.




Question 5
pts


Would the following be a hydrogen donor or acceptor? Or both?




Only a hydrogen acceptor due to the electrons on the oxygen. It is not a
hydrogen donor because the hydrogen atoms are bonded to a carbon.
