Molecular Geometry

Front

What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which affects its physical and chemical properties.

Front

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

Back

Trigonal planar.

Front

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

Back

Tetrahedral.

Front

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

Back

Bent.

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

Back

Trigonal pyramidal.

Front

What determines if a molecule is polar or nonpolar?

Back

The distribution of electron density and the symmetry of the molecule determine its polarity.

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule has no net dipole moment, often due to symmetrical shape or equal sharing of electrons.

Front

How many electrons does hydrogen need to be stable?

Back

2 electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.
