The fundamental difference between the given processes by which gases are formed during the boiling of water and the burning of gasoline is to be explained. Concept Introduction: Covalent bonds are formed by the sharing of electrons between the two electronegative atoms and can be classified as polar or nonpolar on the basis of the atoms involved in them. The overall polarity of a molecule is dependent on the structure of the molecule. If the dipoles cancel each other, then the molecule is nonpolar. Molecules that contain a hydrogen atom bonded to an electronegative element can undergo hydrogen bond formation. A hydrogen bond is formed between a hydrogen atom and an atom of nitrogen, oxygen or fluorine etc. Certain fuels, such as, gasoline or diesel, which are a mixture of hydrocarbons, vaporize when burned, but immediately get oxidized to form carbon dioxide and water vapor.

For the compound: C8H17NO2 Use the following information to come up with a plausible structure: 8 This compound has "carboxylic acid amide" and ether functional groups. The peaks at 1.2ppm are two signals that are overlapping one another. One of the two signals is a doublet that represents 6 hydrogens; the other signal is a quartet that represents 3 hydrogens.
