Question

Which of the following are true statements for the given compound ?



a) HBr : A Bronsted acid and a Lewis acid

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

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

d) Ni 2+(aq) : A Bronsted acid, but not a Lewis acid

e) C6H6 : Both a Bronsted acid and a Lewis acid

Answer 1

a only is correct.

Answer 2

A Bronsted base is maximum in many situations considered a substance which could settle for protons (hydrogen ions), whilst a Lewis base is any molecule or ion which could form a clean coordinate covalent bond, by employing donating a pair of electrons. So a) is actual ammonia can settle for a proton and can donate apair of electrons. unlike a Brønsted-Lowry acid, which continuously transfers a hydrogen ion (H+), a Lewis acid may well be any electrophile (which incorporates H+). in spite of if all Brønsted-Lowry acids are Lewis acids, in easy utilization the term Lewis acid is frequently reserved for those Lewis acids that are no longer Brønsted-Lowry acids. unlike a Brønsted-Lowry acid, which continuously transfers a hydrogen ion (H+), a Lewis acid may well be any electrophile (which incorporates H+). in spite of if all Brønsted-Lowry acids are Lewis acids, in easy utilization the term Lewis acid is frequently reserved for those Lewis acids that are no longer Brønsted-Lowry acids. b) in easy utilization hi is a Brønsted-Lowry acid and consequently no longer considered as a Lewis acid (in spite of if it is). Sp it is actual. c) Acetic acid can donate a proton and so this is a Brønsted-Lowry acid and so it particularly is fake. d) Copper Ion can not donate a proton, so it particularly is fake. e) butane can not donate a proton, so it particularly is fake. precis a and b are actual, whilst c, d and e are fake.
