Among the given platinum(II) complexes, the one that is thermally the most unstable is
(a)
(b)
(c)
(d)
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
Pt(II) dialkyls decompose by β-hydride elimination. Neopentyl (a) and the alkynyls (d) have no β-hydrogen and the platinacyclopentane (b) cannot reach the syn-coplanar geometry; the di-n-butyl complex (c) has accessible β-H and is the least stable.
