Front

According to VSEPR theory, what do molecules adjust their shapes to keep as far away as possible?

Back

Pairs of valence electrons

Front

What is the chemical formula of the ionic compound formed between potassium (K) and sulfur (S)?

Back

K₂S

Front

How would you classify the bonding in a substance with a boiling point of 100⁰C and a heat of vaporization of 2,254 KJ/mol?

Back

Polar covalent - uneven sharing of electrons

Front

Which molecular shape has a bond angle of 180 Degrees?

Back

Linear

Front

Define ionic bonding.

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions.

Front

What is the significance of bond angles in molecular geometry?

Back

Bond angles determine the shape of the molecule, which affects its reactivity and properties.

Front

Explain the concept of VSEPR theory.

Back

VSEPR theory states that the shape of a molecule is determined by the repulsion between electron pairs.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds involve unequal sharing of electrons, while non-polar covalent bonds involve equal sharing.
