1.	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)]` .
Answer» 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` .
