QS1:

A) Given two molecules, CH4 (methane) and CH3OH (methanol), explain why one is non-polar and the other is polar. In your explanation, you must explain the types of bonds formed in each molecule

B) Explain the concept of electronegativity and how it contributes to some of the important characteristic of water.

Ionic bonds are formed when two opposite charged ions (formed when atoms lose or gain electrons) encounter each other. These bonds can be viewed as âextreme polar covalent bondsâ as one atom is in total control of the otherâs electron(s). Why are ionic bonds so much weaker when they are in water?

A.	Ionic compounds such as salts are hydrophilic, so they prefer to form bonds with water molecules over other compounds.

B.	Water molecules readily form covalent bonds to charged particles and, as these bonds are stronger than ionic bonds, the ionic bonds are pulled apart.

C.	Water molecules shorten the size of covalent bonds and this weakens ionic interactions.

D.	Water molecules readily donate electrons and nullify the positively charged ions.

E.	Polar water molecules can physically interfere with the polar (positive/ negative) charged attraction between ions and thus the ionic bonds are disrupted and weakened.

Provide one important example (in the human body) of each of the following:
