Consider four compounds that have nearly the same molecular weights: 1,2-dimethoxyethane, ethyl propyl ether, hexane, and 1-pentanol. Which would you expect to have the highest boiling point? Which would be most soluble in water? Explain the reasons for your choices.

rank the following chemicals in increasinfg order of their solubility in water. Put the least soluble in water first.

Give the true false along with explanation!

Which of these two would be more soluble in water? Why ?

To escape taxes and duties commonly levied upon alcohol, the methanol content in methylated spirits used in solvents is usually up to 5%, and therefore mainly consist of ethyl alcohol (>90%).Name and describe the intermolecular forces that are responsible for methylated spirits to dissolve in a polar solvent such as water.

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?

H2.
