VSEPR theory & molecular shapes

The acronym VSEPR stand for

• very strong electron pair repulsion.

• varied symmetry electrostatic proton reaction.

• venomous snakes enjoy pink ribbons.

• valence shell electron pair repulsion.

What is the VSEPR theory used to predict?

• Bond Strength
• Polarity
• Molecular Shape
• Electronegativity

 A lone pair is defined as

• A pair of bonding electrons
• One non-bonding electron
• A pair of non-bonding electrons
