Organic Molecules1a.How many bonds will an atom of carbon form?_______b.How does this account for the huge variety in structure among organic molecules? ________________________________________________________________________________________c.Carbon forms the “backbone” of organic molecules.Because the organicmolecule to the right is composed of only carbon and hydrogen, it is called a__________________.Is it hydrophilic or hydrophobic? _______________d.Instead of just hydrogen, most organic molecules have various groups ofatoms attached to the carbon backbone.Each group has predictable properties.What are thesegroups called? ___________________________e. As an example, if a hydroxyl group replaces 1 of the hydrogen in the moleculeabove, its chemical properties change.Hydroxyl groups are polar, so is thishydrophilic or hydrophobic? _______________f.When you see a hydroxyl group, you know it likes water but is not ionic.You know its “function”.The same is true for all functional groups.Identify each functional group described below.(Answers are used only once.)(1) ionic group containing phosphorous ______________________(2) acidic functional group ______________________(3) basic functional group ______________________(4) forms disulfide bridges in proteins ______________________2.Polymerizationa.Use the terms monomer and polymer in a sentence describing their relationship._______________________________________________________________
