Chapter 3, problem 18

Which of the following are electrophiles and which nucleophiles

a) H-

b) CH3O-

c) CH3C(triple bond) CH

d) CH3C+HCH3

e) NH3

Electrophiles: d

Nucleophiles; a,b,c,e

Electrophiles are electron loving compounds, they are always looking for a pair of electrons. Electrophiles usually have a positive charge, which is why d is the correct answer

Nucleophile , Electron rich. It has electrons to spare. Most nucleophiles have lone pairs or a negative charge.
