Dedue the value of x in the following compounds.
(a) `[Mo(CO)_(x)]` (b) `[Co_(2)(Co)_(x)]^(2-)`
(c ) `Hx (Cr (CO)_(5)` (d) `HxCo(CO)_(4)`
(c) `[Fe (C_(5)H_(5))_(x)]` (d) `[Cr (C_(6)H_(6))_(x)]` .

Text Solution

Verified by Experts

Refer to solution of above
`EAN = 27 + 1 + x xx 2 = 36, x = 4`(for each Coatom) For two `Co` atoms ` x =8`
(b) `Cr(Z=24)`
`EAN = 1 xx x + 24 + 2 xx 5 = 36, x =2`
(c ) `Co(Z=27)`
`EAN = 1 xx x + 27 + 2 xx 4 =36, x =1`
(d) `Mo(Z =42)`
(Since Mo is a 4d transition element series so atomic weight of next noble gas is `54 Xe `
`:. EAN = 42 + 2x = 54, x =6` .
