Which of the following describes the changes in forces of attraction that occur as H20 changes phase from a liquid to a vapor?

Options are;

(A) H-O bonds break as H-H and O-O bonds form.

(B) Hydrogen bonds between H2O molecules are broken.

(C) Covalent bonds between H2O molecules are broken.

(D) Ionic bonds between H+ ions and OH− ions are broken.

(E) Covalent bonds between H+ ions and H2O molecules become more effective.

B: Hydrogen bonds between H2O molecules are broken.

Explanation:

When water is changing from liquid form to vapour form, it's molecules move at a faster rate. This is because the bonds between the molecules have been broken as a result of the heat that converts the liquid to vapour.

And the type of bond that forms water molecules is hydrogen bonds.

Thus, hydrogen bonds are broken when converting from liquid to vapour phase.

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.
