A) Crown ethers complex alkali metal ions by donation of lone pairs from the oxygen atoms to the metal cation.
B) Metal ion complexes of crown ethers dissolve in nonpolar aprotic organic solvents
C) Addition of 18-crown-6 to a solution of benzyl bromide and potassium cyanide in a nonpolar solvent increases the rate of nucleophilic substitution.
D) 18-Crown-6 is a planar molecule

Question

Quizplus · Accepted Answer
