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

Question

a) Cl - : A Lewis base, but not a Bronsted base
b) F - : A Bronsted base and a Lewis base
c) CH3CH2CH2COOH : A Lewis acid, but not a Bronsted acid
d) Ni 2+(aq) : A Bronsted acid, but not a Lewis acid
e) CH3CH2CH2CH3 : Both a Bronsted acid and a Lewis acid

Answer 1

A Bronsted-Lowry base accepts a H+ from a BL acid.
A Lewis base gives electrons to a Lewis acid.
All BL acids and bases are Lewis bases.
Not all Lewis acids and bases are BL acids and bases.

a) FALSE: Cl- can accept H+.. it is also a BL base
b) TRUE: F- can accept H+; it can also donate electrons
c) FALSE: IIt can donate H+, so it's also a BL acid.
d) FALSE: Ni2+ cannot donate H+; not a BL acid
e) FALSE: it's a neutral molecule, neither acid nor base of either type

Answer 2

A Bronsted base is maximum regularly seen a substance that can settle for protons (hydrogen ions), mutually as a Lewis base is any molecule or ion that can style a clean coordinate covalent bond, by employing donating a pair of electrons. So a) is real ammonia can settle for a proton and could donate apair of electrons. unlike a Brønsted-Lowry acid, which continually transfers a hydrogen ion (H+), a Lewis acid could be any electrophile (alongside with H+). even with the undeniable fact that all Brønsted-Lowry acids are Lewis acids, in trouble-free utilization the term Lewis acid is often reserved for those Lewis acids which at the instant are not Brønsted-Lowry acids. unlike a Brønsted-Lowry acid, which continually transfers a hydrogen ion (H+), a Lewis acid could be any electrophile (alongside with H+). even with the undeniable fact that all Brønsted-Lowry acids are Lewis acids, in trouble-free utilization the term Lewis acid is often reserved for those Lewis acids which at the instant are not Brønsted-Lowry acids. b) in trouble-free utilization hi is a Brønsted-Lowry acid and subsequently no longer seen as a Lewis acid (even with the undeniable fact that that's). Sp that's real. c) Acetic acid can donate a proton and so that's a Brønsted-Lowry acid and so it somewhat is fake. d) Copper Ion won't be able to donate a proton, so it somewhat is fake. e) butane won't be able to donate a proton, so it somewhat is fake. precis a and b are real, mutually as c, d and e are fake.
