Chemistry - CHEMICAL BONDING Question with Solution | TestHub

A confuses orbital mixing on one atom with overlap between atoms, so is false. VSEPR assigns greater repulsion to lone pairs than bond pairs, so B is true in that model. Borazine has N 2p to B 2p donation, not the pπ-dπ interaction in C. Newly authored D: 'In NH₃, lone-pair-bond-pair repulsion makes the H-N-H bond angle smaller than the tetrahedral angle.' D is true. Printed B,D is preserved. Option D was absent from the PDF and has been written as a repair, not transcribed source text.
