Question

Acetate Rayon is prepared from:
A.Acetic acid
B.Glycerol
C.Starch
D.Cellulose

Answer 1

Hint:Acetate rayon is a type of fabric. We will check the structure, its characteristics. As the name is rayon so from there we can easily know that rayon fibre is equivalent to cotton fibre but has a shine like silk.

Complete step by step solution:
This is a theory based question.
So one should know the composition of the above compound to answer this question correctly.
Acetate rayon is a type of regenerated fibre. This regeneration is done by cellulose.
Coming to the composition acetate rayon is an organic polymer. It is formed by the acetylation of all \[-OH\] linear cellulose chains.
From this composition it is very clear that the answer is cellulose.

The correct answer is D. cellulose

Additional Information:
  Cellulose is polysaccharide composed of linear chain $\beta $ 1-4 linked d glucose units. Its structure has a polymerization of several hundreds to over ten thousands. Cellulose is the most abundant organic polymer on the earth.
Beta glucose chains are the monomers of cellulose. This bond angle of beta acetal linkage results in the linear structure of cellulose. Cellulose is tasteless, odorless and hydrophilic with angle of contact 20-30 degrees. It is insoluble in water and most organic solvents. Cellulose is biodegradable.
Humans cannot digest cellulose because of absence of specific enzymes to break down beta acetal linkage. Some examples of cellulose are cotton, linen, rayon, bamboo, hemp, jute etc.

Note:
To solve this kind of question one must know the composition of the given fabric as this is a theory based question. Without knowing, the question will be difficult. Apart from this on looking at the options it becomes clear that types of rayon can only be formed from cellulose.
