VSEPR REVIEW

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 of molecules based on the repulsion between electron pairs.

Front

How many lone pairs are present in a trigonal pyramid molecular shape?

Back

1

Front

What is the bond type in P2 molecules?

Back

Covalent bonds with 3 shared electron pairs.

Front

In covalent bonds, how are electrons treated?

Back

Electrons are shared between atoms.

Front

What is a lone pair in the context of VSEPR theory?

Back

A pair of non-bonding electrons on the central atom.

Front

What molecular shape is associated with 4 bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What molecular shape is formed when there are 2 bonding pairs and 2 lone pairs?

Back

Bent or angular.

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 3 bonding pairs and 1 lone pair?

Back

Trigonal pyramidal.
