Question

(a) What type to compound is CH3COOH?
(b) What substance should be oxidised to prepare CH3COOH?
(c) What is the physical state of CH3COOH?
(d) State one advantage of soaps over detergents.

Answer 1

Answer:

a) CH3COOH is carboxylic acid

it is an organic compound of carbon, hydrogen and oxygen

b) alcohol CH3CH2OH is oxidized to prepare CH3COOH

C) It is liquid at room temperature and freeze at 290K

Answer 2

(a) $C H 3 C O O H$ is the organic compound and it is called ethanoic acid.

(b) $C H 3 C O O H$ can be prepared by oxidising ethanol.

(c) $C H 3 C O O H$ is seen in liquid state.

(d) Soaps are biodegradable, whereas the detergents are not biodegradable.

Explanation:

• $C H 3 C O O H$ is a carboxylic acid. It is called ethanoic acid, which is also called acetic acid.  
• It is one of the simplest carboxylic acids. It has one methyl group attached to it. It is an industrial chemical and an important chemical reagent used for cellulose acetate production that is used for photographic film, fabrics and synthetic fibres.
• Soaps are degradable, so they don’t pollute environment. However, some of the detergents are not biodegradable, so they pollute environment.
