Question

Given below are two statements:
Statement (I): 2:1 layer silicates consist of two tetrahedral sheets bound to either side of an octahedral sheet.
Statement (II): Two tetrahedral sheets of 2:1 layer silicates is bound to one side of an octahedral sheet in 2:1 layer silicates.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Remember the layer ratios:
- 1:1 Minerals (e.g., Kaolinite) $\rightarrow$ 1 tetrahedral sheet + 1 octahedral sheet.
- 2:1 Minerals (e.g., Montmorillonite) $\rightarrow$ 2 tetrahedral sheets sandwiching 1 octahedral sheet.

Answer 1

The Correct Option is C
