Which of the following information(s) is/are incorrect regarding the voids formed in three dimension — Solid State Chemistry Question

💡 Solution & Explanation

Statement C describes an octahedral void (two opposed triangular voids stacked together), not a tetrahedral void. Statement D describes a trigonal prismatic void; true octahedral voids occur when the triangular voids in two layers point in opposite directions and do not exactly overlap. Thus, statements C and D are incorrect. Therefore, correct answer is C,D.
