A Lewis acid accepts an electron pair.
The correct answer is acid.
A Lewis acid.
The correct answer is acid.
An acid accepts an electron pair from a base.
If an atom donates or accepts an electron it is considered an ion.
NAD is an electron/H carrier in respiration and NADP is an electron/H carrier in photosynthesis.
A Lewis acid accepts an electron pair from a base. ---APEX--
There are three definitions. A substance that produces hydroxide (OH-) ions in water. A substance that accepts a proton (H+ ion). An electron pair donor.
As the definition of a Lewis acid says:"Capable of accepting electron pair (from a (Lewis) base".So H+ and Ag+ are both Lewis acids compared in the following reaction with ammonia:(in which the N-atom is donating the unbound electron pair as being a 'Lewis' base)H+ + NH3 --> HNH3+Ag+ + 2NH3 --> Ag(NH3)2+[As you can see the 'Lewis' definition is much wider than the 'Bronsted/Lowry': it needs free places for an electron pair, not H+]
according to Lewis theory acids act as electron pair acceptors bases act as electron pair donors
they are the same. Lone pair is unshared pair of electrons and bond pair is shared pair of electron.
