VSEPR Theory

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.

Any molecule with only two atoms must be linear. Three-atom molecules such as BeCl₂ can also be linear. For linear molecules, the bond angle is

• $360\degree$

• $180\degree$

• $120\degree$

• $90\degree$

Molecules such as boron trichloride that have three bonded atoms and no unshared pairs have what shape?

• trigonal planar

• trigonal pyramidal

• trigonal bipyramidal

• tetrahedral

What molecular geometry would PH₃ have?

• Trigonal Pyramidal

• Trigonal Bipyramidal

• Bent

• Linear

What shape would this have?

• Trigonal planar

• Pyramidal

• Tetrahedral

• Bent

According to VSEPR, molecules adjust their shapes to keep which of the following as far away as possible?

• Pairs of valence electrons
• Inner shell electrons
• Mobile Electrons
• Electrons closest to the nucleus

*

• linear
