This section contains multiple choice questions. Each question has 4 choices (a), (b), (c) and (d), out of which ONLY ONE is correct. Cellulose on treatment with sodium hydroxide gives (a) mercerised cotton (b) \(\mathrm{D} \cdot(+)\) -glucose (c) pyroxylin (d) xanthate

Short Answer

Expert verified
Answer: Mercerised cotton

Step by step solution

01

Recall the reaction of cellulose with sodium hydroxide

When cellulose, a natural polysaccharide found in plant cell walls, reacts with sodium hydroxide (NaOH), it undergoes a chemical transformation called mercerisation. This process involves breaking some of the hydrogen bonds between cellulose chains, leading to a more crystalline structure. The end product is mercerised cotton, which has improved strength, luster, and dye-affinity.
02

Identify the correct option

Given the information above, we can now identify the correct option: (a) mercerised cotton Therefore, the correct answer to the multiple choice question is option (a).

(b) The intermolecular forces in thermoplastics are weaker than those present in elastomers. (c) There are no cross links between polymeric chain. (d) Neoprene is a thermoplastics polymer.

Give reasons for the following statements. (i) o- and p-nitrophenols can be separated by steam distillation. (ii) Sodium fusion extract has to be neutralized with dil.HNO \(_{3}\) before testing for the halogen with \(\mathrm{AgNO}_{3^{*}}\) (iii) Benzene does not decolourise bromine water though it contains three double bonds. (iv) Lassaigne's test for nitrogen is not given by diazonium compound. (v) Sodium fusion extract is boiled with \(\mathrm{HNO}_{3}\) for testing for halogen, if nitrogen and sulphur are present.

This section contains multiple choice questions. Each question has 4 choices (a), (b), (c) and (d), out of which ONLY ONE is correct. An ice cold solution of aniline in \(\mathrm{HCl}\) is treated with \(\mathrm{NaNO}_{2}\). The compound (A) thereby formed is tested for nitrogen using Lassaigne's test. The result would be (a) a Prussian blue colour confirming the presence nitrogen in aniline. (b) a green colour confirming the presence of nitrogen in aniline (c) an absence of any coloured solution to confirm the presence of nitrogen (d) evolution of ammonia which gives a colour with Nessler's reagent.
