Vedclass · Answer

(A) Bronsted acid is defined as a substance that has a tendency to donate a proton $(H^{+})$. Conversely,a Lewis acid is defined as a substance that is capable of accepting a lone pair of electrons. $H_{3}O^{+}$,$NH_{3}$ (as a conjugate acid),and $HCl$ contain $H^{+}$ ions and can act as Bronsted acids. $BF_{3}$ is an electron-deficient molecule with an incomplete octet on the boron atom,making it an electron pair acceptor,which classifies it as a Lewis acid.

Identify a species which is not a Bronsted acid but a Lewis acid.
