Reaction A will be Carried out in a fume Cupboard. True or False

Let's continue with these questions.

6. Reaction A will be carried out in a fume cupboard. True or False.
True. Reaction A involves ethanoic acid and concentrated sulfuric acid, both of which have strong fumes and are corrosive. Performing it in a fume cupboard ensures proper ventilation and safety.

7. What effect does reaction B have on litmus paper?
Reaction B (ethanol + ethanoyl chloride) produces hydrogen chloride gas. This gas, when dissolved in water (e.g., on moist litmus paper), forms hydrochloric acid, which will turn blue litmus paper red.

8. What gas will be given off in the reaction in B?
The gas given off in reaction B is hydrogen chloride ($\text{HCl}$).

9. Ethanol, 2-propanol, and 2-methyl-2-propanol reacted with Sodium Metal. What is the increasing order of reactivity?
The increasing order of reactivity of these alcohols with sodium metal is:
2-methyl-2-propanol < 2-propanol < ethanol.
(Tertiary alcohols are less reactive than secondary, which are less reactive than primary alcohols, due to steric hindrance and electron-donating effects of alkyl groups).

10. What gas was given off on the reaction?
When alcohols react with sodium metal, hydrogen gas ($\text{H}_2$) is given off.

11. The reactions are carried out in clean freshly washed test tube. True or False.
True. Using clean and dry glassware is essential for accurate and safe chemical experiments, especially in organic reactions where impurities or water can interfere.

12. What caution should be taken in the experiment?
When reacting alcohols with sodium metal, several cautions are important:

• Wear safety goggles to protect eyes from splashes.
• Use small pieces of sodium as the reaction can be vigorous.
• Keep away from flames or ignition sources because hydrogen gas, which is flammable, is produced.
• Ensure all glassware is dry as sodium reacts violently with water.
