A) \[{{\left[ S{{i}_{4}}{{O}_{11}} \right]}^{6\,-}}\]
B) \[{{\left[ Si{{O}_{4}} \right]}^{4\,-}}\]
C) \[{{\left[ S{{i}_{2}}{{O}_{7}} \right]}^{2\,-}}\]
D) \[{{\left[ S{{i}_{3}}{{O}_{9}} \right]}^{3\,-}}\]
Correct Answer: A
Solution :
Molecular formula of asbestos is \[\operatorname{Ca}.M{{g}_{3}}O\left( S{{i}_{4}}{{O}_{11}} \right)\] in which silicate is present as\[{{\left( S{{i}_{4}}{{O}_{11}} \right)}^{4\,-}}\]. Some of \[SiO_{4}^{-}\] tetrahedra share. Three oxygen and other shares two oxygen atom. This is an example of double chain silicates.You need to login to perform this action.
