Question

Which of the following are true statements for the given compound in aqueous solution ?


a) HBr : A Bronsted acid and a Lewis acid

b) HCN : A Lewis acid, but not a Bronsted acid

c) CH3COOH : A Lewis acid, but not a Bronsted acid

d) Fe 3+(aq) : A Lewis acid, but not a Bronsted acid

e) CH3CH2CH2CH3 : Neutral, not an acid or base of any kind

Answer 1

I think everybody's doing acid/base theory right now!
And why does nobody use "Bronsted-Lowry" anymore?
Was Lowry defrocked ?

Anyway, a) and d) are true, but so is e)
The molecule in e) will not form ions in solution, so it can't be an acid or a base.

Answer 2

It's amazing how many times this question has come up over the last few days! Is everybody out there doing the same homework at the same time?

a and d are true.

Answer 3

A Bronsted base is maximum regularly considered as a substance that ought to settle for protons (hydrogen ions), even as a Lewis base is any molecule or ion that ought to style a sparkling coordinate covalent bond, with techniques from donating a pair of electrons. So a) is actual ammonia can settle for a proton and ought to donate apair of electrons. compared to a Brønsted-Lowry acid, which continuously transfers a hydrogen ion (H+), a Lewis acid must be any electrophile (which include H+). even with the actual shown truth that one and all Brønsted-Lowry acids are Lewis acids, in elementary utilization the time period Lewis acid is often reserved for those Lewis acids that are literally not Brønsted-Lowry acids. compared to a Brønsted-Lowry acid, which continuously transfers a hydrogen ion (H+), a Lewis acid must be any electrophile (which include H+). even with the actual shown truth that one and all Brønsted-Lowry acids are Lewis acids, in elementary utilization the time period Lewis acid is often reserved for those Lewis acids that are literally not Brønsted-Lowry acids. b) in elementary utilization hi is a Brønsted-Lowry acid and hence not considered as a Lewis acid (even with the actual shown truth that that is). Sp that is actual. c) Acetic acid can donate a proton and so that is a Brønsted-Lowry acid and so it is fake. d) Copper Ion can not donate a proton, so it is fake. e) butane can not donate a proton, so it is fake. precis a and b are actual, even as c, d and e are fake.
