PS Molecular Geometry and polarity

Front

What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which affects its physical and chemical properties.

Front

What is polarity in molecules?

Back

Polarity in molecules refers to the distribution of electrical charge over the atoms in a molecule, leading to regions of partial positive and negative charge.

Front

What type of bond is formed between two nonmetals?

Back

A covalent bond is formed between two nonmetals.

Front

What is the shape of a molecule with two bonding pairs and no lone pairs?

Back

Linear.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What is the shape of a molecule with three bonding pairs and one lone pair?

Back

Trigonal pyramidal.

Front

What is the shape of a molecule with two bonding pairs and two lone pairs?

Back

Bent.

Front

What determines the polarity of a molecule?

Back

The polarity of a molecule is determined by the difference in electronegativity between the bonded atoms and the molecular geometry.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of chemical bond where electrons are shared unequally between two atoms, resulting in a molecule with a partial positive and partial negative charge.
