Front

What is hybridization in chemistry?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals, which can be used to form chemical bonds in molecules.

Front

What is the hybridization state of sulfur in sulfur hexafluoride (SF6)?

Back

Front

Back

The molecular geometry is octahedral.

Front

How many sigma and pi bonds are present in 1,3-butadiene?

Back

1,3-butadiene has 9 sigma bonds and 2 pi bonds.

Front

What is the hybridization of the central atom in phosphorus pentachloride (PCl5)?

Back

Front

Back

The molecular geometry is trigonal bipyramidal.

Front

Define sigma bond.

Back

A sigma bond is a type of covalent bond formed by the direct overlap of atomic orbitals, allowing for free rotation around the bond axis.

Front

Define pi bond.

Back

A pi bond is a type of covalent bond formed by the side-to-side overlap of p orbitals, which restricts rotation around the bond axis.

Front

What is the hybridization state of a molecule with a trigonal planar geometry?

Back

Front

Back

The molecular geometry is trigonal planar.
