VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the main principle of VSEPR theory?

Back

Molecules adopt shapes that minimize the repulsion between electron pairs.

Front

What shape does a molecule with 4 bonding pairs and no lone pairs have?

Back

Tetrahedral.

Front

What is the molecular shape of NH3 (ammonia)?

Back

Trigonal pyramidal.

Front

How does the presence of lone pairs affect molecular shape?

Back

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

Front

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

Back

Bent.

Front

Is CO2 a polar or nonpolar molecule?

Back

Nonpolar.

Front

What type of bond is present in a Cl2 molecule?

Back

Covalent nonpolar bond.

Front

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

Back

Trigonal pyramidal.

Front

What is the effect of symmetry on molecular polarity?

Back

Symmetrical molecules are typically nonpolar.
