Study Notes

Che8 is a chemical compound with a molecular formula of CHE8H6O5. It belongs to the class of organic compounds known as substituted phenols. As a result, it contains an aromatic ring made up of six carbon atoms where one hydroxyl group is attached to the fifth carbon atom in the ring. This single bonded oxygen molecule makes the compound polar due to electronegativity differences between oxygen and carbon.

The IUPAC name of che8 is derived from its parent structural unit, which is benzene and the functional groups present on the aromatic ring. Therefore, the IUPAC name of che8 would be 1-(hydroxyethyl)benzene. The presence of the hydroxyl group (-OH) in the substituent indicates that che8 can act as both a Lewis base and a Lewis acid under different conditions.

In terms of physical properties, che8 has a melting point range of approximately 59°C to 60°C. Its boiling point is 235°C at 760 mmHg. The compound is soluble in water and ethanol, but insoluble in ether and chloroform, indicating that che8 is polar due to its hydroxyl group.

The synthesis of che8 involves the reaction of ethanol with benzaldehyde in the presence of an acid catalyst, such as sulfuric acid. The reaction proceeds through a series of steps, including nucleophilic addition and dehydration, to form che8.

In summary, che8 is a polar organic compound with a melting point range of 59°C to 60°C. It is soluble in water and ethanol but insoluble in ether and chloroform. Its synthesis involves the reaction of ethanol with benzaldehyde in the presence of an acid catalyst. The compound has an IUPAC name of 1-(hydroxyethyl)benzene.
