Chapter 7: Problem 81

Cellulose \(\frac{(\mathrm{i}) \mathrm{CS}_{2} / \mathrm{NaOH}(\mathrm{aq})}{\text { (ii) dil HCl }}\) (A) (A) obtained in the above treatment of cellulose is known as (a) Cellulose xanthate (b) Cellulose sulphide (c) viscose rayon (d) Gun cotton

Short Answer

Expert verified
Answer: (a) Cellulose xanthate

Step by step solution

01

Treatment with CS2/NaOH

First, cellulose is treated with carbon disulfide (CS2) and sodium hydroxide (NaOH) in an aqueous solution. This treatment of cellulose forms a yellow-orange compound, which is known as cellulose xanthate.
02

Treatment with dilute HCl

The cellulose xanthate, formed in the previous step, is then treated with dilute hydrochloric acid (HCl). This treatment results in the formation of a viscous solution, which is called viscose. The chemical structure of viscose includes the cellulose xanthate group.
03

Identifying the Product (A)

Based on the given reactions and their respective product formations, it becomes clear that the product obtained after these treatments, (A), is indeed cellulose xanthate. So, the correct answer is: (a) Cellulose xanthate

A mixture of aniline and paranitrobenzoic acid can be separated by using (a) only con. HCl (b) only \(\mathrm{NaHCO}_{3}\) solution (c) only con.HNO \(_{3}\) (d) either conc.HCl or \(\mathrm{NaHCO}_{3}\)

An organic compound (A) gives violet colour with neutral \(\mathrm{FeCl}_{3}\). It answers Liebermann's test. This compound on catalytic reduction gives (B). The saturated compound (B) on oxidation with \(\mathrm{CrO}_{3}\) gives (C) of molecular formula \(\mathrm{C}_{6} \mathrm{H}_{10} \mathrm{O}\). (C) gives precipitate with 2,4 -dinitrophenylhydrazine. (C) can be obtained by reductive ozonolysis of (D). The other product of reductive ozonolysis, (E), undergoes Cannizzaro reaction with benzaldehyde to give (F) and HCOONa. Answer the following questions. Arrange in order of increasing acidity of (i) (A) (ii) p-nitrophenol (iii) p-methylphenol (iv) \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) (a) (iv) \(<(\mathrm{iii})<(\mathrm{i})<(\mathrm{ii})\) (b) \((\mathrm{iv})<(\mathrm{iii})<(\mathrm{ii})<(\mathrm{i})\) (c) \((\mathrm{i})<(\mathrm{iv})<(\mathrm{iii})<(\mathrm{ii})\) (d) (ii) \(<(\mathrm{iv})<(\mathrm{iii})<(\mathrm{i})\)
