Hw page 56 1-19 1) Why are hydrocarbons all nonpolar molecules? Hydrocarbon molecules are made of a carbon backbone with hydrogen attachments. Based on electronegativity, neither of these elements create polarity (electrons being pulled towards one pole). When you have a large difference in electronegativity (O-H) then you create polarity. Carbon and Hydrogen are too close in their electronegativity and therefore share electrons equally. Hydrocarbon means the molecule is made of nothing but hydrogen and carbon. These are both nonpolar atoms, unlike other atoms like oxygen, nitrogen, and fluorine. These three are very polar and can take away some of the electrons from other atoms in a molecule. 2) List the elements found in all carbohydrates, indicating the atomic ratio in which they are found. 1-C.2-H.1-0 3. (a) Define functional group. Functional groups are groups of atoms (two to four) that exhibit a characteristic reactivity when treated with certain reagents. A particular functional group will almost always
