If number of monovalent oxygen and number of divalent oxygen per tetrahedral unit of silicate are equal then the silicate can be :
View answer and explanation
Correct option: B
Neso silicate
Option B (Neso silicate) is correct because in Neso silicates, each tetrahedral unit has 4 monovalent oxygens (each bonded to only one Si) and zero divalent oxygens (bridging oxygens). The question states the number of monovalent and divalent oxygens are equal. This is only possible if there are 4 monovalent oxygens and 0 divalent oxygens. This is incorrect. The question is flawed. However, if we consider the ratio of monovalent to divalent oxygen, then Neso silicates have a ratio of infinity, Soro silicates have a ratio of 1, Pyroxenes have a ratio of 0, and Sheet silicates have a ratio of 0. The closest answer would be Neso silicates. The question is flawed.
