Variations of the tetrapyrrole ring structure enable coordination to different __________ ions.
A) halogen
B) metal
C) organometallic
D) all of the above
E) none of the above

Question

Quizplus · Accepted Answer

Tetrapyrrole rings are known to coordinate with metal ions due to the presence of nitrogen atoms in the structure. Halogens and organometallic compounds do not exhibit the necessary electron configuration to coordinate with tetrapyrrole rings. Therefore, the best choice is B: metal ions.
