What is the primary constituent of sand?(a) Silicon tetroxide(b) Silica(c) Silicon(d) FeldsparThis question was posed to me in a job interview.This is a very interesting question from P-Block Elements topic in division P-Block Elements of Chemistry – Class 12

Answer» CORRECT answer is (b) SILICA

To explain I would say: Sand is primarily composed of silicon dioxide, also called silica. Silicon tetroxide is not a COMPOUND but an oxo-anion of silicon. Silicon METAL does not form native in nature and feldspar is a mineral ore consisting of several TECTOSILICATE compounds.
