A positive Lucas test on phenol would indicate that phenol is a strong enough acid to react with Lucas reagent (a mixture of concentrated hydrochloric acid and zinc chloride) to form a cloudy solution or a precipitate. This reaction distinguishes phenol from other alcohols that do not react with the Lucas reagent.
When an Elodea leaf is added to a phenol red solution, the leaf will release oxygen through photosynthesis. The oxygen will cause the phenol red solution to change color, indicating the presence of oxygen production.
Phenol should always be stored in a closed container. If it overheats it could build pressure causing it to explode. It could also produce toxic or irritating fumes.
Ozone when heated gets decomposed. It decomposes into oxygen.
it goes up
When phenol reacts with concentrated nitric acid (HNO3) in the presence of sulfuric acid (H2SO4), a mixture of products is formed, including picric acid (2,4,6-trinitrophenol) and water. This reaction is known as nitration of phenol and is used to synthesize picric acid, which is a yellow, explosive compound.
To convert phenol to 2,4,6-trinitrophenol (picric acid), you would first nitrate phenol by treating it with a mixture of nitric and sulfuric acids. This will lead to the substitution of hydrogen atoms on the phenol ring with nitro groups, resulting in the formation of the 2,4,6-trinitrophenol compound.
copper sulphate and hydrogen is released.
There is formation of ethoxy ethane. (ether)
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
Phenol reacts with concentrated sulfuric acid to form the sulfonated product, and then with concentrated nitric acid to form picric acid (2,4,6-trinitrophenol).
To prepare phenyl benzoate from phenol, first convert phenol to phenyl benzoate by reacting it with benzoic acid and a catalyst such as concentrated sulfuric acid or concentrated hydrochloric acid at elevated temperatures. This esterification reaction will yield phenyl benzoate along with water as a byproduct. Purification techniques such as distillation can then be used to isolate the desired product.
When litharge (lead(II) oxide) is heated with concentrated sulfuric acid (H2SO4), lead sulfate (PbSO4) is formed along with water. The reaction is as follows: PbO(s) + H2SO4(l) → PbSO4(s) + H2O(l)
tribromophenol is formed.
When concentrated sulfuric acid is heated with oxalic acid, oxidation of oxalic acid takes place, giving off carbon dioxide gas and water as byproducts. This reaction can be used to generate carbon dioxide for various applications.
A positive Lucas test on phenol would indicate that phenol is a strong enough acid to react with Lucas reagent (a mixture of concentrated hydrochloric acid and zinc chloride) to form a cloudy solution or a precipitate. This reaction distinguishes phenol from other alcohols that do not react with the Lucas reagent.
