Chapter 4.2: Bronsted-Lowry Acids and Bases

Question 1

What is the species formed when an acid transfers a proton to a base?

Answer 1

conjugate base

Question 2

What is the result of a proton-transfer reactions that occur with compounds having pi electrons?

Answer 2

 The result of the proton-transfer reaction is formation of a carbocation, a species in which one of its carbons has only six electrons in its valence shell and carries a charge of +1

Question 3

What is a conjugate acid-pair?

Answer 3

o Any pair of molecules or ions that can be interconverted by transfer of a proton is called a conjugate acid-base pair

Question 4

Answer 4

the species formed when a base accepts a proton from an acid
