Question

Which set can associate without requiring an initially empty acceptor orbital on the atom that joins the partner? Consider ethyl radicals forming butane, NO radicals forming a spin-paired dimer, propanoic acid forming its cyclic vapour dimer, and GaCl₃ forming a halogen-bridged dimer.

TestHub · Accepted Answer

Radical association pairs singly occupied orbitals; the acid dimer uses hydrogen bonds. Neither mechanism needs the empty Lewis-acid orbital used by GaCl₃ to accept a chloride lone pair from its partner. This distinguishes electron pairing and hydrogen bonding from donor-acceptor bridging.
