Select all correct statements. Use spin-only moments, ignore ring conformations, and use ionic electron counting for organometallics.
Options:(select one or more)
Answer:
A, B, D
Solution:
A: Co(II), d⁷ tetrahedral, has three unpaired electrons; NO has one. B: the bis-chelate has three stereoisomers and the tris-chelate has two. C: H₃PO₂ has two P−H bonds; H₃PO₄ has none, so total two, not three. D: Cr⁰ supplies six electrons plus twelve from two η⁶-arenes; Mn⁻ supplies eight plus ten from CO. Both are 18-electron species.
