Question

What would be the bond type (covalent, polar covalent, ionic) for both B-H bonds in BH2? Explain in a short sentence.

Answer 1

Answer: non-polar covalent

Step-by-step explanation:

If two atoms have an electronegativity difference of 0.4 or less, they form a non-polar covalent bond.

B is 2.04 electronegativity

H is 2.20 electronegativity

the electronegativity difference is 0.16.

this is less than 0.4 so the bonds are non-polar covalent.
