Question

1.Отличие фенолов от одноатомных спиртов проявляется в реакции: а) с калием; б) со спиртами; в) со щелочами;

Answer 1

Фенол - карболовая кислота, фенол проявляет слабые кислотные свойства. Он может взаимодействовать со щелочами, как кислота
C6H5OH + KOH = C6H5OK + H2O

Answer 2

Difference Between Phenols and Monohydric Alcohols in Reaction

The difference between phenols and monohydric alcohols in their reaction can be observed in their reactions with potassium, with other alcohols, and with alkalis.

a) With Potassium: - Phenols react with potassium to form potassium phenoxide and hydrogen gas. - Monohydric alcohols also react with potassium to produce potassium alkoxide and hydrogen gas.

b) With Other Alcohols: - Phenols do not react with other alcohols under normal conditions. - Monohydric alcohols can undergo esterification or dehydration reactions with other alcohols.

c) With Alkalis: - Phenols react with alkalis to form water-soluble salts. - Monohydric alcohols do not react with alkalis under normal conditions.

These differences in reactions are due to the unique chemical properties of phenols compared to monohydric alcohols.
