It is known that the sulfhydryl group,^-SH,forms strong coordinate bonds to certain heavy metal ions.Which of the following do you expect to be the best chelating agent for heavy metal ions? A)HS-CH₂-CH(SH)-CH₂-OH B)H-SH C)CH₃-SH D)CH₃-S-S-CH₃ E)SO₄^2-

Question

Quizplus · Accepted Answer

Option A is the best chelating agent for heavy metal ions because it contains multiple sulfhydryl (SH) groups, which can form strong coordinate bonds with heavy metal ions, increasing its chelation capability.
