1c. What is the polarity of Acetone, C3H6O?

1d. What is the dominant intermolecular force of Acetone, C3H6O?

1e. What is the dominant intermolecular force of Methyl alcohol, CH3OH?

Solutions

Expert Solution

1 a. NaCl is a strong electrolyte as we add more salt to the water its concentration will increase. this will leads to a decrease in the conductance of the solution.

1b.1 c. Acetone molecules are polar because of the positive and negative charges formed by their carbonyl group. However these molecule don't produce any H+ ions in polar solvent like water. therfore these are called polar aprotic solvents.

1d. Acetone molecules are attracted by both dipole-dipole interactions and London forces.These kind of intramolecular forces give rise to vanderwaal interaction which held together the molecules.

1e. . Methanol is polar compound and will therefore exhibit dipole -dipole interactions. It also contains the -OH alcohol group which will allow for hydrogen bonding ,this leads to vanderwaal interaction which increase the interaction between the molecules.

Perhaps you recall that when table salt, NaCl, is added to water, the freezing point of water is lowered. Consider a system composed of a mixture of 2.5kg of ice and 50g of liquid water and a small, separate container of finely powdered salt. This physical system is contained in a fully insulated container that prevents all thermal interactions with the environment. Both the salt and the ice-water mixture are initially at the freezing point of water, 0 °C. The...
