The student is now told that the four solids, in no particular order, are aluminum chloride (AlCl3AlCl3), sugar (C6H12O6C6H12O6), benzoic acid (C6H5COOHC6H5COOH), and sodium bromide (NaBrNaBr). Assuming that conductivity is correlated to the number of ions in solution, rank the four substances based on how well a 0.20 MM solution in water will conduct electricity.

The order of conductivity will be as follows:

> NaBr > Benzoic acid > sugar

Explanation:

ionizes to give one Al and three ions and thus, produces 4 ions.

Sugar does not ionizes and hence does not produce ions.

Benzoic acid is a weak organic acid and ionizes to produce two ions; and .

Sodium bromide is a strong electrolyte and ionizes to produce 2 ions.

As sodium is strong electrolyte, therefore, its conductance will be higher than benzoic acid.

Therefore, the order of conductivity will be as follows:

> NaBr > Benzoic acid > sugar

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
