Which describes the structure of a water molecule, h2o? it has two polar single bonds and a bent shape. it has two nonpolar single bonds and a bent shape. it has two nonpolar single bonds and a linear shape. it has two polar single bonds and a linear shape

- First choice is correct, "It has two polar single bonds and a bent shape."

Explanations:- In water, O atom is the central atom and two H atoms are bonded with a single bond by the sharing of electrons to the central atom. Since there is a sharing of electrons, the bonds between O and H atoms are covalent.

Oxygen atom is more electron negative as compared to H atom, so the shared electrons are more towards oxygen atom and it generates a partial negative charge on O and partial positive charge on H atoms and makes the bond polar covalent.

The molecule would be linear if the central atom doesn't have lone pair of electrons. Since, there are two lone pair of electrons around O atom, there becomes repulsion between two lone pairs and the lone pairs and bond pairs also and the molecule becomes asymmetrical and it's shape becomes bent.

So, the water molecule has two polar single bonds and a bent shape.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
