Question

How many of the following names are incorrect? (a) [Fe(η⁵-C₅H₅)₂]: bis(η⁵-cyclopentadienyl)iron(II). (b) [Cr(C₆H₆)₂]: bis(η⁶-benzene)chromium(0). (c) H₂[PtCl₆]: hexachloridoplatinate(IV) hydride. (d) [Al(OH)(H₂O)₅]SO₄: pentaaquahydroxidoaluminium(III) sulphate. (e) K₃[Fe(CN)₅NO]: potassium pentacyanidonitrosylferrate(II). (f) [Co(NH₃)₅(ONO)]²⁺: pentaamminenitrito-N-cobalt(III) ion. (g) [CoCl₂(en)₂]⁺: bis(ethane-1,2-diamine)dichloridocobalt(III) ion.

Answer:

3

Solution:

(c) is wrong; it should be dihydrogen hexachloridoplatinate(IV). (f) is wrong because ONO is nitrito-O. (g) is wrong because alphabetical order gives dichlorido before bis(ethane-1,2-diamine). Names (a), (b), (d), (e) are correct. Count = 3.
