WebLewis Acids are Electrophilic meaning that they are electron attracting. When bonding with a base the acid uses its lowest unoccupied molecular orbital or LUMO (Figure 2). Various species can act as Lewis acids. All … WebThere are also Lewis acids and bases, which is a different theory about acid base chemistry. The Bronsted-Lowery definition refers to the loss or gain of an H+ (proton). The acid is a proton donor, and the base is a proton acceptor. The Arrhenius definition of an acid is an H+ producer and the base is an OH- producer.
