VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion

Front

What is the primary purpose of VSEPR theory?

Back

To predict the molecular shape based on electron pair repulsion.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, altering the shape.

Front

What is the molecular shape of a molecule with 4 bonding pairs and no lone pairs?

Back

Tetrahedral

Front

What is the molecular shape of a molecule with 3 bonding pairs and 1 lone pair?

Back

Trigonal pyramidal

Front

What is the molecular shape of a molecule with 2 bonding pairs and 2 lone pairs?

Back

Bent or angular

Front

What type of bond is formed when electrons are shared equally?

Back

Nonpolar covalent bond

Front

What type of bond is formed when electrons are shared unequally?

Back

Polar covalent bond

Front

Which molecule is an example of a nonpolar molecule?

Back

CH₄ (methane)

Front

What is the effect of electronegativity on bond polarity?

Back

Differences in electronegativity between atoms determine bond polarity.
