Polarity

Front

What is polarity in chemistry?

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond. A polar molecule has a partial positive charge on one end and a partial negative charge on the other.

What type of bond is formed between lithium (Li) and chlorine (Cl)?

Back

Ionic bond.

Front

Which compound consists of nonpolar molecules: H2S, PH3, AsH3, or SiH4?

Back

SiH4.

Front

What molecular shape has unshared pairs of electrons on the central atom?

Back

Bent.

Front

Which of the following molecules is polar: a only, b only, a and b, or a and c?

Back

a and c.

Front

What kind of bond is formed between sulfur (S) and oxygen (O)?

Back

Polar covalent bond.

Front

Define a non-polar covalent bond.

Back

A non-polar covalent bond is a type of chemical bond where two atoms share a pair of electrons with each other equally.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where a pair of electrons is unequally shared between two atoms, leading to a partial charge.

Front

What is the significance of electronegativity in determining polarity?

Back

Electronegativity is the ability of an atom to attract electrons. The difference in electronegativity between two atoms determines whether the bond is non-polar, polar, or ionic.

What is the shape of a molecule with two bonded atoms and one lone pair?

Back

Bent.
