CDL Ch 8 Covalent Bonding Review

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

Which elements typically form covalent bonds?

Back

Nonmetals typically form covalent bonds with each other.

Front

What is the molecular formula for diphosphorus pentoxide?

Back

P₂O₅

Front

What shape does a linear molecule have?

Back

A linear molecule has a straight-line shape with bond angles of 180 degrees.

Front

What is the shape of a bent molecule?

Back

A bent molecule has a shape where the bond angles are less than 180 degrees due to lone pairs on the central atom.

Front

How do you determine the shape of a molecule?

Back

The shape of a molecule can be determined using the VSEPR (Valence Shell Electron Pair Repulsion) theory.

Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity determines how strongly an atom attracts shared electrons in a covalent bond.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where the electrons are not shared equally between the two atoms.

Front

What is the difference between a single bond and a double bond?

Back

A single bond involves one pair of shared electrons, while a double bond involves two pairs of shared electrons.

Front

What is the bond angle in a tetrahedral molecule?

Back

The bond angle in a tetrahedral molecule is approximately 109.5 degrees.
