VSEPR

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the basic principle of VSEPR theory?

Back

The shape of a molecule is determined by the repulsion between electron pairs in the valence shell.

Front

What molecular geometry is associated with 3 bonded atoms and 0 lone pairs?

Back

Trigonal planar.

Front

What molecular geometry is associated with 2 bonded atoms and 1 lone pair?

Back

Bent.

Front

What is the molecular geometry of PBr3?

Back

Trigonal pyramidal.

Front

How many electron pairs are involved in determining the shape of a molecule according to VSEPR theory?

Back

Both bonding pairs and lone pairs of electrons.

Front

What is the molecular geometry for a molecule with 4 bonded atoms and 0 lone pairs?

Back

Tetrahedral.

Front

What is the effect of lone pairs on molecular geometry?

Back

Lone pairs occupy more space than bonding pairs, affecting the overall shape.

Front

What is the bond angle in a trigonal planar molecule?

Back

120 degrees.
