An acid accepts an electron pair from a base.
Br can act as a Lewis base by donating its lone pair of electrons to form a coordinate covalent bond with a Lewis acid.
In a Lewis acid-base reaction, a Lewis acid (electron pair acceptor) reacts with a Lewis base (electron pair donor) to form a coordination complex. The Lewis acid accepts electron pairs from the Lewis base, resulting in the formation of a coordinate covalent bond between the two species.
Lewis acid is an electron acceptor / Lewis base is an electron donor. It is helpful to use this definition of acid and base in (1) organic chemistry (2) also when there are no Hydrogens present in the molecule. BF3 is a Lewis acid it seeks out and can accept electrons.
Hydrazine can act as both a Lewis base and a Lewis acid. As a Lewis base, it can donate a lone pair of electrons to form a coordinate covalent bond with a Lewis acid. As a Lewis acid, it can accept a lone pair of electrons from a Lewis base to form a coordinate covalent bond.
Cl can act as both a Lewis acid and a Lewis base depending on the reaction it is involved in. As a Lewis acid, Cl can accept an electron pair and form a coordinate covalent bond. As a Lewis base, Cl can donate an electron pair to form a bond.
Formaldehyde (CH2O) is not typically considered a Lewis acid or base on its own. Its role as an acid or base would depend on the specific reaction conditions and the species it is interacting with.
AlCl3 is a Lewis acid because it can accept a pair of electrons from a Lewis base to form a coordinate covalent bond.
H3O+ is considered a Lewis acid because it can accept an electron pair from a Lewis base.
No, water is not a Lewis acid. It is a Lewis base because it donates a lone pair of electrons to other compounds to form a coordinate covalent bond.
CH4 (methane) is a neutral molecule and is neither a Lewis acid nor a Lewis base. Lewis acids are electron pair acceptors, while Lewis bases are electron pair donors. Since CH4 does not have any available lone pairs to donate or accept, it does not exhibit Lewis acid or base behavior.
