Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the main purpose of VSEPR theory?

Back

To predict the molecular shape of a molecule based on the repulsion between electron pairs.

Front

How many electrons does hydrogen need to achieve a stable configuration?

Back

2 electrons.

Front

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

Back

Tetrahedral.

Front

According to VSEPR theory, what do molecules adjust their shapes to minimize?

Back

The repulsion between pairs of valence electrons.

Front

In a covalent bond, how many electrons are shared in a single bond?

Back

2 electrons.

Front

What is a polar covalent bond?

Back

A bond where electrons are shared unequally between atoms, resulting in a partial charge.

Front

What is the difference between a single bond and a double bond?

Back

A single bond shares 2 electrons, while a double bond shares 4 electrons.

Front

What is electronegativity?

Back

The ability of an atom to attract electrons in a bond.

Front

What molecular shape is formed when there are two bonding pairs and two lone pairs?

Back

Bent.
