What determines if a molecule is polar or non-polar?

Back

The distribution of electron density and the shape of the molecule determine its polarity. If the molecule has a symmetrical shape and equal sharing of electrons, it is non-polar. If it has an asymmetrical shape with unequal sharing of electrons, it is polar.

Front

What is the molecular geometry of H2S?

Back

H2S has a bent molecular geometry due to the presence of lone pairs on the sulfur atom, which causes repulsion and results in a non-linear shape.

Front

What is the definition of ionic bonds?

Back

Ionic bonds are formed when one atom transfers electrons to another atom, resulting in the formation of positively and negatively charged ions that attract each other.

Front

In ionic bonds, what do metals tend to do?

Back

Metals tend to lose valence electrons.

Front

What is the significance of electronegativity in determining molecular polarity?

Back

Electronegativity is the ability of an atom to attract electrons. A significant difference in electronegativity between atoms in a bond can lead to polar covalent bonds, contributing to molecular polarity.

Front

What is a polar molecule?

Back

A polar molecule is one that has a net dipole moment due to the presence of polar bonds and an asymmetrical shape, resulting in a positive and negative end.

Front

What is a non-polar molecule?

Back

A non-polar molecule is one that has no net dipole moment, often due to symmetrical shape and equal sharing of electrons.

Front

What is the role of lone pairs in molecular geometry?

Back

Lone pairs occupy space and can affect the shape of a molecule by repelling bonding pairs, leading to different molecular geometries.
