What two conditions must exist for a molecule to be polar?

For a molecule to be polar, two conditions must be met:1-We must have at least one polar bond or one lone pair on the central atom. 2-If there are more than one polar bond, they must be arranged in a way that their dipoles do not cancel.

What does it mean if a molecule is polar quizlet?

1. A) What does it mean when a molecule is said to be “polar.” It means that it has an unevenly distributed electrical charge. A water molecule is polar because the electric charge is distributed unevenly because the oxygen atom is on one end, causing it to have a slight negative and a slight positive charge.

What determines if a molecule is polar or nonpolar quizlet?

The type of atoms in a molecule and its shape are factors that determine whether a molecule is polar or nonpolar. How do attractions between polar molecules compare to attractions between nonpolar molecules? Attractions between polar molecules are stronger than attractions between nonpolar molecules.

Why is water called a polar molecule quizlet?

water is called polar molecule, its two hydrogen atoms are joined to one oxygen atom by single covalent bonds, but the electrons of the covalent bonds are not shared equally between oxygen and hydrogen this unequal sharing makes water a polar molecule.

What properties does water have because it is a polar molecule quizlet?

Because water is a polar molecule, it is able to form multiple hydrogen bonds, which account for many water’s special properties. How does water’s polarity influence its properties as a solvent? Water’s polarity gives it the ability to dissolve both ionic compounds and other polar molecules.

How do hydrogen bonds form quizlet?

A hydrogen bond is formed between adjacent water molecules when a negative end of one water molecule is attracted to the positive end of another water molecule.

Which properties of water make it an important component of blood?

Because salt content affects the density of water, water contributes to the circulation of the oceans, thus affecting the global climate. Furthermore, its solubility is vital to biological processes such as osmosis and has an important role as the main component of blood plasma.
