Question

Which metal species is most likely to be involved in the oxidative addition reaction by an organometallic complex?

            (a) Mn                          (b) V                           (c) Ir                             (d) Y

Answer 1

Answer Loxidatione Ir option (c) is addition reaction correct is done as : Ln M t Oxidation State o } y → Ln M Oxidations y stale = +2 A Note : - Metal should be in low oxedations slate for election density should more on metal There should be suitable vacant orbital on metal so that it can accomodate é density provided by legand . on moving down the group, rate of oxidative addition increases as effective nuclear charge decreases to election density is easily available It belongs to 5d series. Rect of them either belong to za or td series. Jolal number of election available with It is maximum. It has 5d7 682 ie q e- while Iva 5e - May 7e- and y ze The two unit higher oxedation state should be en Ir +1) and Ir(+3) both are very stable - Please rate! esto
