Which of the following crown ether solvates potassium ions?

Question

Quizplus · Accepted Answer

Crown ethers are cyclic polyethers that can serve as complexing agents for metal cations, including potassium ions. The number in the name of the crown ether refers to the number of atoms in the ring, while the "crown" term comes from the resemblance of the ring to a crown. The size of the ring and the number of oxygen atoms in the ring determine the selectivity and affinity of the crown ether for different metal ions. In this case, 18-crown-6, with a ring size of 18 atoms and six oxygen atoms, is the best choice for solvating potassium ions.
