VSEPR and Covalent Lewis Dots (Chem Q2W4 Flashcard 24-25)

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 geometry of molecular structures based on electron pair repulsion.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

How does the presence of lone pairs affect molecular shape?

Back

Lone pairs repel more strongly than bonding pairs, altering the geometry.

Front

What is the predicted shape of the hydrogen chloride (HCl) molecule according to VSEPR theory?

Back

Linear.

Front

What is a characteristic feature of metallic compounds?

Back

They have a 'sea' of delocalized electrons.

Front

What is the shape of a molecule with two bonding pairs and one lone pair?

Back

Bent.

Front

What is the shape of a molecule with five bonding pairs and no lone pairs?

Back

Trigonal bipyramidal.

Front

What is the shape of a molecule with four bonding pairs and one lone pair?

Back

Seesaw.

Front

What is the molecular geometry of carbon tetraiodide (CI4)?

Back

Tetrahedral.
