VSEPR Practice

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 is the molecular shape of CH₄?

Back

tetrahedral.

Front

What is the molecular shape of NH₃?

Back

trigonal pyramidal.

Front

What is the molecular shape of H₂S?

Back

bent.

Front

What is the molecular shape of BF₃?

Back

trigonal planar.

Front

How does lone pair repulsion affect molecular shape?

Back

Lone pairs occupy more space than bonding pairs, leading to adjustments in the molecular geometry.
