Title: Does [Cr (C6H6) 2] follows Ean rule?
Post by: Kushagra Joshi on February 04, 2020, 02:56:30 PM

For me I don't think that it follows the Ean rule but my teacher says it follows, can you give a proper explanation for this question.

It does. Chromium⁰ has [Ar]3d⁵4s¹ configuration and the two benzene supply 12 electrons so in sum it is 18 electrons what gives  a stable complex.
