What is the nature of the bond between B and O in (C₂H₅)₂ OBH₃?

What is the nature of the bond between B and O in (C₂H₅)₂ OBH₃?

Options

(a) Covalent
(b) Coordinate Covalent
(c) ionic bond
(d) Banana shaped bond

Correct Answer:

Coordinate Covalent

Explanation:

In (C₂H₅)₂ OBH₃ coordinate bond is formed in between B and O.
(C₂H₅)₂O → BH₃
(C₂H₅)₂O gives one lone pair of electron to BH₃. So, it is called electron pair donor and BH₃ is called electron pair acceptor.
