Atom economy ( atom efficiency/percentage) is the conversion efficiency of a chemical process in terms of all atoms involved and the desired products produced. The simplest definition was introduced by Barry Trost in 1991 and is equal to the ratio between the mass of desired product to the total mass of products, expressed as a percentage.

Definition of a Hydrogen bond: H-bonds form when both A and B are strongly electronegative atoms (N, O or F) and B possesses a lone pair of electrons with which to attract the H atom. The H attached to an electronegative atom is the Hydrogen bond donor. The electronegative atom which coordinates to this H is the Hydrogen bond acceptor.
