Test: Hybridization/Sigma & Pi Bonds

Front

What is hybridization?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can accommodate the bonding requirements of atoms in a molecule.

Front

What is sp hybridization?

Back

sp hybridization occurs when one s orbital and one p orbital mix to form two equivalent sp hybrid orbitals, typically seen in linear molecules.

Front

What is sp² hybridization?

Back

sp² hybridization occurs when one s orbital and two p orbitals mix to form three equivalent sp² hybrid orbitals, typically seen in trigonal planar molecules.

Front

What is sp³ hybridization?

Back

sp³ hybridization occurs when one s orbital and three p orbitals mix to form four equivalent sp³ hybrid orbitals, typically seen in tetrahedral molecules.

Front

What are sigma bonds?

Back

Sigma bonds are the first bonds formed between two atoms, created by the head-on overlap of orbitals, allowing for free rotation.

Front

What are pi bonds?

Back

Pi bonds are formed by the side-to-side overlap of p orbitals, occurring in double and triple bonds, restricting rotation.

Front

How many sigma bonds are in a single bond?

Back

A single bond consists of one sigma bond.

Front

How many pi bonds are in a double bond?

Back

A double bond consists of one sigma bond and one pi bond.

Front

How many pi bonds are in a triple bond?

Back

A triple bond consists of one sigma bond and two pi bonds.

Front

What is the hybridization of a carbon atom in methane (CH₄)?

Back

The hybridization of carbon in methane is sp³.
