 3C6H5CH3+4KMnO4+2H2O=3C6H5COOH+4MnO2+4KOH 

Answer 2

1) The given sequence of chemical reactions involves the conversion of various compounds. Let's break it down step by step:

a) CH3COH: This is the chemical formula for ethanol, which is an alcohol commonly known as ethyl alcohol or drinking alcohol.

b) C2H5OH: This is also the chemical formula for ethanol. So, CH3COH and C2H5OH are the same compound.

c) C2H5Br: This is the chemical formula for ethyl bromide, which is an alkyl halide.

d) C2H4: This is the chemical formula for ethene, also known as ethylene. It is an unsaturated hydrocarbon and is commonly used in the production of plastics.

e) CH3COH: This is ethanol, as mentioned earlier.

f) CH3COONH4: This is the chemical formula for ammonium acetate, which is a salt formed by the reaction of acetic acid (CH3COOH) with ammonia (NH3).

2) Let's now analyze the second sequence of reactions:

a) C2H4: This is ethene or ethylene, as mentioned earlier.

b) C2H4Cl2: This is 1,2-dichloroethane, which is an organic compound used as a solvent and in the production of vinyl chloride.

c) C2H2: This is ethyne or acetylene, which is an unsaturated hydrocarbon commonly used in welding and as a starting material for the synthesis of various organic compounds.

d) C6H6: This is benzene, which is a cyclic hydrocarbon with a ring of six carbon atoms. It is an important industrial solvent and is used as a starting material for the production of various chemicals.

e) C6H5CH3: This is toluene, which is an aromatic hydrocarbon commonly used as a solvent and as a starting material for the production of chemicals such as benzene and xylene.

f) C6H5COOH: This is benzoic acid, which is a carboxylic acid commonly used as a food preservative and in the production of various chemicals.

Please note that the given sequences of reactions involve the conversion of different compounds, and each compound has its own properties and uses. If you have any specific questions about any of these compounds or reactions, feel free to ask!
