What is a hybrid orbital?

An orbital that exists only in hybrid molecules

An orbital whose shape is a hybrid of the shapes of different types of orbitals

A theoretical space that does not contain electrons

An orbital that can only be found in the s sub-level

Answer explanation

A hybrid orbital is an orbital whose shape is a hybrid of the shapes of different types of orbitals, combining characteristics from each.

What is the significance of the term "hybridization" in chemistry?

It refers to the creation of hybrid animals

It is the process of determining the molecular shape

It describes the mixing of atomic orbitals to form new orbitals for bonding

It is the process of combining two different elements to form a compound

Answer explanation

The term 'hybridization' in chemistry refers to the mixing of atomic orbitals to form new orbitals for bonding.

When atoms form covalent bonds, what happens to the space between the two atoms?

The space remains empty

The space is filled with hybrid orbitals

The space is occupied by ionic bonds

The space becomes a vacuum

Answer explanation

When atoms form covalent bonds, the space between them is filled with hybrid orbitals, allowing for the sharing of electrons.

What is the geometry of molecules with four electron cloud regions such as tetrahedral, trigonal pyramidal, or bent with single bonds (like H2O)?

Linear

Trigonal planar

Tetrahedral

Octahedral

Answer explanation

Molecules with four electron cloud regions, like H2O, have a tetrahedral geometry due to the arrangement of single bonds around the central atom.

What type of hybrid orbital is formed by one s and three p orbitals?

sp

sp^2

sp^3

d^2sp^3

Answer explanation

One s orbital and three p orbitals combine to form sp^3 hybrid orbitals, where one s orbital and three p orbitals mix together to create four equivalent sp^3 hybrid orbitals.
