What is a covalent compound?

Back

A covalent compound is a chemical compound formed by the sharing of electrons between two or more nonmetal atoms.

Front

What is the general formula for a covalent compound?

Back

There is no single formula; covalent compounds can have various formulas depending on the elements involved, e.g., H2O for water.

Front

What type of bond is formed in covalent compounds?

Back

Covalent bonds are formed by the sharing of electron pairs between atoms.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in a molecule with a slight electrical dipole moment.

Front

What is the significance of unshared pairs of electrons in molecular geometry?

Back

Unshared pairs of electrons can affect the shape of a molecule and its bond angles, influencing its overall geometry.

Front

How do you determine the shape of a covalent molecule?

Back

The shape can be determined using the VSEPR (Valence Shell Electron Pair Repulsion) theory, which considers the repulsion between electron pairs.

Front

What is the shape of a molecule with two bonded pairs and one unshared pair of electrons?

Back

The shape is bent or angular.

Front

What is the difference between a single bond and a double bond in covalent compounds?

Back

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

Front

What is the name of the covalent compound CO2?

Back

Carbon dioxide.
