Question

Which of the following properties correctly explain the compound $ Si{O_2} $
(A) Linear, basic
(B)Tetrahedral, acidic
(C) Tetrahedral, basic
(D) Linear, acidic

Answer 1

Hint :When one silicon atom combines with two oxygen atoms then a single molecule of silicon dioxide is formed. The molecular formula of silicon dioxide is $ Si{O_2} $ . Silicon dioxide exists in different forms.

Complete Step By Step Answer:
Silicon dioxide ( $ Si{O_2} $ ) also known as silica. Silicon dioxide exists in different forms like quartz, flint, opal. Silica is present in a form of white crystalline solid. The crystalline form of silicon dioxide is known as quartz. The molecular weight of silicon dioxide is $ 60.08g/mol $ . Silicon dioxide molecules are present in nature and the molecule shape of silicon dioxide is linear.
Silicon dioxide is an oxide of silicon and silicon oxide is an acidic oxide because when it reacts with base to produce a salt. It is a silicate salt.
Hence option D is a correct option. Silicon dioxide is a linear, acidic oxide of silicon.

Additional Information:
Silicon dioxide at room temperature present in the form of solid. And silicon dioxide is not dissolved in water.
The melting point of Silicon dioxide is $ {1713^O}C $
The density of Silicon dioxide is $ 2.648g/c{m^3} $
The boiling point of Silicon dioxide is $ {2950^O}C $
Silicon dioxide is present in the earth crust in $ 2nd $ most large amount.

Note :
Silicon dioxide is used in many ways the crystalline form of silicon dioxide is used as hydraulic fracturing. This method is used to obtain petroleum from the earth.
Mainly Silicon dioxide is used as a sedative (used as more sleepiness).
In a toothpaste Silicon dioxide is used to remove tooth plaque and also help in removing yellowish material that accumulates in the tooth. Silicon dioxide is used as a production of elemental silicon.
