Determine the bonding type for boron trihydride given the electronegativity on the pauling scale for boron is 2.0 and for hydrogen is 2.1.

The bond between boron and hydrogen in boron trihydride is covalent bond.

Explanation:

The type of bonding between the atoms forming a compound is determined by using the electronegativity difference between the atoms. According to the pauling's electronegativity rule:

We are given:

Electronegativity for boron = 2.0

Electronegativity for hydrogen = 2.1

As, is less than 1.7 and not equal to 0. Hence, the bond between boron and hydrogen is covalent bond.
