B₂H₆ reacts with two molecules of diethyl ether to form two BH₃·O(C₂H₅)₂ adducts. Which statements are correct in the elementary local model?
Options:(select one or more)
Answer:
A, B, D
Solution:
Each ether oxygen donates one pair into a boron acceptor orbital. The monomeric product has three B–H directions and one B–O direction, conventionally tetrahedral/sp³. Formation of two monomer adducts opens the original bridges. A coordinate-bond label tracks electron-pair origin; it does not mean the final bond lacks shared density.
