B) A bond has regions of high electron density lying above and below the bond axis, which is the line connecting the two atoms.
C) A bond commonly is formed from the overlap of two unhybridized atomic 2p orbitals.
D) In the trigonal planar geometry, the bonds are formed from the overlap of an sp² hybridized orbital with another orbital.
