A transition metal M forms a volatile chloride which has a vapour density of 94.8 . If it contains 74.75 % of chlorine the formula of the metal chloride will be

Options

  1. AMCl ₃
  2. BMCl ₂
  3. CMCl ₄
  4. DMCl ₅

Correct answer

C. MCl ₄

Step-by-step solution

74.75 % of chlorine means 74.75 ~g chlorine is present in 100 ~g of metal chloride. Weight of metal =100 ~g -74.75 ~g =25.25 ~g Equivalent weight aligned & = weight of metal weight of chlorine 35.5 & = 25.25 74.75 35.5=12 aligned Valency of metal array r = 2 V.D. Equivalent wt. of metal +35.5 = 2 94.8 12+35.5 =4 array Formula of compound = MCl ₄
