Some Basic Concepts Of Chemistry Question 60

Question: 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:

A) $ MCl _3 $

B) $ MCl _2 $

C) $ MCl _4 $

D) $ MCl _5 $

Show Answer

Answer:

Correct Answer: C

Solution:

[c] 74.75% of chlorine means 74.75g chlorine is present in $ 100g $ of metal chloride. Weight of metal = $ 100g-74.75g $ $ =25.25g $ Equivalent weight $ =\frac{weightofmetal}{weightofchlorine}\times 35.5 $ $ =\frac{25.25}{74.25}\times 35.5=12 $ Valency of metal $ =\frac{2\times V.D.}{Equivalentwt.ofmetal+35.5} $ $ =\frac{2\times 94.8}{12+35.5}=4 $

$ \therefore $ Formula of compound $ =MCl _4 $
