Question

C6H6 + K2O ---> ?C6H6 + C2H5OH ---> ?C6H6 + C6H16 ---> ?

Answer 1

Вторая реакция - алкилирование бензола:
С6Н6 + С2Н5ОН -(Н3РО4)-> С6Н5С2Н5 + Н2О

Answer 2

The chemical reactions you've provided involve benzene (C6H6) reacting with different compounds. Here are the products for each reaction:

1. C6H6 + K2O → ? (Reaction with potassium oxide) The reaction between benzene and potassium oxide does not result in a direct reaction or product. Benzene is not expected to react with K2O under normal conditions.

2. C6H6 + C2H5OH → ? (Reaction with ethanol) When benzene reacts with ethanol (C2H5OH) under suitable conditions, it can undergo a substitution reaction known as an electrophilic aromatic substitution. The reaction is typically catalyzed by a Lewis acid such as aluminum chloride (AlCl3). The product of this reaction is ethylbenzene (C6H5C2H5).

3. C6H6 + C6H16 → ? (Reaction with hexane) Benzene does not undergo a direct reaction with hexane (C6H16) under normal conditions. These compounds do not readily react with each other.

To summarize:

1. C6H6 + K2O → No direct reaction
2. C6H6 + C2H5OH → C6H5C2H5 (ethylbenzene)
3. C6H6 + C6H16 → No direct reaction
