Chapter 4.7: Lewis Acids and Bases

Question 1

Define protic acid

Answer 1

an acid that is a proton donor in an acid-base reaction

Question 2

What is a nucleophile?

Answer 2

• We call the electron-rich species a nucleophile (nucleus-loving), meaning that it is seeking a region of low electron density

Question 3

Define aprotic acid

Answer 3

an acid that is not a proton donor; an acid that is an electron pair acceptor in a Lewis acid-base reaction

Question 4

What is an acid that is not a proton donor; an acid that is an electron pair acceptor in a Lewis acid-base reaction?

Answer 4

aprotic acid

Question 5

What is an electrophile?

Answer 5

• We call the low electron-density species an electrophile (electron-loving) meaning that it is seeking a region of high electron density
