26 TM complexes
Consider the five structures shown. Which of these five can act as ligands forming complexes with transition metals?
Select one:
a. Ligands (a), (d) and (e).
b. Only ligand (e).
c. Ligands (a) and (b) only.
d. Structures (a) and (e) only.
e. Ligands (b) and (c) only.
Homework Answers
Correct answer is option A) ligands a,d and e
Ligands are generally lewis bases. That is they have lone pairs of electrons to donate.
We see that in the above given molecules only a,d,e have lone pairs of electrons making them act as ligands.
