Question

write a chemical reaction for tollens reagent test with ethanol​

Answer 1

2(Ag(NH)2)OH+C2H5OH =C2H4O+2Ag+4NH3+2H2O

hope this will be helpful for you

Answer 2

Tollens reagent does not react with ethanol​but undergoes a small amount of oxidation and forms black precipitate and silver metal is separated out.

Explanation:

• Tollens reagent is used to distinguish between aldehydes and ketones functional groups.
• It is a mixture of silver nitrate, ammonia, and some amount of sodium hydroxide.
• The chemical formula of Tollens reagent is $AgNO_{3} + NH_{4}OH$
• Tollen's reagent is also known as the silver mirror test.
• It is the qualitative test to identify the aldehydes and ketones.
• It is said that Tollen's reagent does not react with Alcohol.
• When primary alcohol reacts with tollens reagent it undergoes oxidation and gives black precipitate.
• Chemical reaction is as follows -

$2(Ag(NH)_{2} )OH+C_{2} H_{5} OH =C_{2} H_{4} O+2Ag+4NH_{3} +2H_{2}$
