Vedclass · Answer

(A) Lewis acid is an electron pair acceptor,while a Bronsted acid is a proton $(H^{+})$ donor.$1$. $CO_{2}$: It has no $H$ atom to donate,so it is not a Bronsted acid. It acts as a Lewis acid by accepting electron pairs from bases like $OH^{-}$.$2$. $BCl_{3}$: It has an incomplete octet (electron deficient),acting as a Lewis acid. It has no $H$ atom,so it is not a Bronsted acid.$3$. $NO_{2}^{+}$: It is electron deficient (positive charge),acting as a Lewis acid. It has no $H$ atom,so it is not a Bronsted acid.$4$. $NH_{3}$ and $CH_{3}NH_{2}$: These are Bronsted bases (proton acceptors) and Lewis bases (electron pair donors).$5$. $C_{6}H_{5}NH_{3}^{+}$: This is a Bronsted acid as it can donate a proton.Therefore,the species that are only Lewis acids but not Bronsted acids are $CO_{2}, BCl_{3}$,and $NO_{2}^{+}$.

Which of the following species are only Lewis acids but not Bronsted acids from $CO_{2}$,$BCl_{3}$,$NH_{3}$,$CH_{3}NH_{2}$,$NO_{2}^{+}$,and $C_{6}H_{5}NH_{3}^{+}$?
