How many joules of heat are required to heat 24.5 g of ethyl alcohol from the prevailing room temperature, 22.5 oC, to its boiling point, 78.5 oC? The Specific Heat of Ethyl Alchohol = 2.138 J/goC a) 3.0 * 10^4 b) 4.11 X10^3 c) 2.93 * 10^3 d) 2.9 * 10^4 e) 1.18 * 10^3

Draw 3 structural isomers of isoamyl alcohols. Two must be an alcohol and one must be an ether.

Rules: • Compounds with the capability of forming hydrogen bonds have stronger intermolecular forces than compounds which have polar bonds/dipole-dipole forces. • Carboxylic acids have 2 hydrogen bonding sites, therefore carboxylic acids have stronger hydrogen bonds than alcohols. • Compounds with one hydrogen bond are soluble in water. The solubility limit is 5 carbons for every one hydrogen bond, this means a compound that has 2 hydrogen bonds can dissolve in water with 10 carbons. • Compounds capable of forming hydrogen bonds have the highest melting point and boiling point. Answer the following questions: 1. Match the hydrocarbons provided with the relevant physical property. You may find it useful to draw Lewis structures to find your answer. C2H6, C12H24, CH4, CeHe . Highest intermolecular force? H&C Lowest intermolecular force? Molecule with the highest boiling point? Soluble in water? Lowest Boiling point?
