MCDB Study Group Day 1 Water 1. Polarity a. Water is a polar molecule i. Explaination- unshared electrons(o), electronegativity is >.4 ii. Why is it important?- It’s a solvent for all polar molecules and a solvent in cytoplasm iii. Hydrogen has a low electronegativity of 2.2, anything with hydrogen is low iv. What makes a molecule more or nonpolar -You can see how polar it is by the electronegativity of the molecules. O is more electronegative and takes more of the e- than H does which makes it polar. CH4 is nonpolar because C+H have about the same electronegativity and since they share and equal attraction makes it nonpolar. v. Ethanol(C2H5OH) is polar because OH don’t have a similar electronegativity

Unformatted text preview: vi. Ethane(C2H6) is non polar because of eletrnegativity vii. How will Ethane and Ethanol react in water? 1. Ethane wont react in water because its not polar, but ethanol will because its polar 2. NaCl is soluble in water because it is an ionic bond and they are broken in water, causing NaCl to break down and dissole. 2. Bond Type a. What types of bonds are associated with water and why? i. Covalents bonds because H and O are shared ii. Hydrogen bonds between polar molecules and since H2O is polar and has H 3. Properties of covalent, ionic, hydrogen a. covalent occurs when e- are shared, b. hydrogen occurs between polar molecules c. Ionic occurs during a transfer of e-...
