Sigma and Pi Bonding

Front

What is a sigma bond?

Back

A sigma bond is a type of covalent bond formed by the direct overlap of atomic orbitals, allowing for the sharing of electrons between two atoms.

Front

What is a pi bond?

Back

A pi bond is a type of covalent bond formed by the side-to-side overlap of p orbitals, occurring in addition to a sigma bond between two atoms.

Front

How many sigma bonds are in a double bond?

Back

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

Front

How many sigma bonds are in a triple bond?

Back

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

Front

What is the maximum number of sigma bonds that can be formed between two atoms?

Back

The maximum number of sigma bonds that can be formed between two atoms is one.

Front

How many pi bonds are in a single bond?

Back

A single bond has 0 pi bonds.

Front

What is the relationship between sigma and pi bonds in a molecule?

Back

In a molecule, every double bond has one sigma bond and one pi bond, while every triple bond has one sigma bond and two pi bonds.

Front

Can a pi bond exist without a sigma bond?

Back

No, a pi bond cannot exist without a sigma bond; it always accompanies a sigma bond.

Front

What type of orbitals overlap to form a sigma bond?

Back

Sigma bonds are formed by the head-on overlap of s or p orbitals.

Front

What type of orbitals overlap to form a pi bond?

Back

Pi bonds are formed by the lateral overlap of p orbitals.
