What is meant when a molecule is described as being polar?

What is meant when a molecule is described as being polar?

A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. A dipole is any molecule with a positive end and a negative end, resulting from unequal distribution of electron density throughout the molecule.

Is a water molecule polar explain your answer?

Water is a polar molecule. While the overall charge of the molecule is neutral, the orientation of the two positively charged hydrogens (+1 each) at one end and the negatively charged oxygen (-2) at the other end give it two poles.

Which statement best describes why a water molecule is polar?

Water is a polar molecule because the bonds between oxygen and hydrogen are polar covalent bonds. This means that although they form covalent bonds (normally non-polar) the difference in electronegativity is great enough to make one side more negative (oxygen side) and the other side more positive (hydrogen side).

What are the characteristics of polar molecules?

A polar molecule is a molecule that has a mostly positive charge on one side and a mostly negative charge on the other. This charge difference allows the positive end of the molecule to attract to the negative end of another. A hydrogen bond, a special attraction between some polar molecules, is another important characteristic.

Does water have polar bonds?

The polar bond in water exists because hydrogen has a lower electronegativity, directly influenced by the number of electrons it tends to draw to itself in a covalent bond: one to oxygen’s two.

Is water a polar covalent compound?

Water is a polar solvent, but covalent compounds are usually nonpolar. This means covalent compounds typically don’t dissolve in water, instead making a separate layer on the water’s surface.

What is the most common polar molecule?

Water is the most polar molecule because a bond between oxygen and hydrogen has the most difference out of the atoms listed. Although the oxygen has two hydrogens bonded, this does not decrease the electronegativity of oxygen, but oxygen unfairly shares sets of electrons from both hydrogens, making it more polar still.
