The terms "bent" and "V-shape" are often used interchangeably, and they generally refer to the same molecular geometry. Both terms describe a molecular shape where three atoms are arranged around a central atom in a way that resembles an open angle, forming a V shape. The angle between the two outer atoms is typically less than 180 degrees.
In the context of molecular geometry and hybridization, molecules with a bent or V-shaped structure often involve sp3 hybridization. For example, water (H₂O) is a common molecule with a bent or V-shaped geometry. In the water molecule, the oxygen atom is sp3 hybridized, and the two hydrogen atoms are arranged in a V shape around the oxygen.
So, while "bent" and "V-shaped" are used interchangeably, the hybridization associated with such molecular geometries is often sp3. It's important to note that these terms describe the shape of molecules rather than the specific hybrid orbitals involved, but sp3 hybridization is commonly associated with these geometries.
