Chemical Bonding And Molecular Structure Question 127

Question: The molecular formula of chloride of a metal M is $ MCl_3. $ The formula of its carbonate would be [CPMT 1987]

Options:

A) $ MCO_3 $

B) $ M_2{{( CO_3 )}_3} $

C) $ M_2CO_3 $

D) $ M{{( CO_3 )}_2} $

Show Answer

Answer:

Correct Answer: B

Solution:

As the molecular formula of chloride of a metal M is $ MCl_3 $ , it is trivalent so formula of its carbonate will be $ M_2{{(CO_3)}_3} $ .
