Answer:
According to valence bond theory the expected valency of boron is three.
Explanation:
Valence bond theory explains about bond formation between the atoms in a molecule.
It states that sharing of electrons occurs by overlapping of orbitals.
Boron has electronegetivity value 2 or 3. So it gets easily reduced and looses 3 electrons instead gaining 5 electrons.
Hence valency of Boron is 3.
