Ethanol and dimethyl ether has same molecular formula, C 2 H 6 O. The reason behind the fact that dimethyl ether has a boiling point that is lower than the boiling point of ethanol is to be explained. Concept Introduction: The various kinds of interactions that bind a molecule together are known as intermolecular forces. These forces can be dispersion, dipole-dipole, ion-dipole, and hydrogen bonding. The boiling point of a substance depends upon the intermolecular forces present in a molecule. When hydrogen is covalently bonded to a very small, highly electronegative atom (usually fluorine, oxygen, or nitrogen), the result is a molecule with a large dipole moment. This leads to a particularly strong type of dipole–dipole attraction traditionally called hydrogen bonding

Essential oils are concentrated liquid containing metabolites extracted from plant sources and are widely used in the production of perfumes. The structures of some of these compounds present in essential oils, along with acetone, are presented below. CH3 H2C CH H2 H3CO, CH2 CH H2C H2C CH FCH2 HO H3C CH2 Compound A MM: 164.2 g/mol Boiling Point: 254 C Compound B MM: 162.19 g/mol Boiling Point: 232 C Compound C MM: 136.24 g/mol Boiling Point: 176 C Determine the most possible boiling point of each of the compounds. Refer to the possible boiling points listed above. An equal volume of COMPOUNDS A, B and C were stored in separate beakers which were left uncovered at room temperature. 1. 2. If the three liquids were allowed to stand for about 10 minutes, which of the following will have the least amount of liquid b. What physical property is the basis of the answer?

Ethanol and dimethyl ether have the same molecular formula C2H6O. Ethanol is liquid at room teperature while dimethyl ether is gas. How is this possible? Explain.

Chemistry 1. Glycerol, CH2(OH)CH(OH)CH2OH, has a 3 carbon chain with -OH groups coming off of each carbon. This thick, syrup like liquid is used in anti-freeze and as a food additive. Hexaoctane, C18H38, is a greasy wax-like solid at room temperature. Using this information rank molecules in order of increasing boiling point and justify your answer: PCl2F, H2O, SeS3, MgS, Glycerol, CH4, CaS, PF2Cl, Hexaoctane, Ne
