#1
Front (Question)

Define protic acid

Back (Answer)

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

#2
Front (Question)

What is a nucleophile?

Back (Answer)

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

#3
Front (Question)

Define aprotic acid

Back (Answer)

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

Back (Answer)

aprotic acid

#5
Front (Question)

What is an electrophile?

Back (Answer)

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