what is the product formed when ethanol is reacted with sulfuric acid (in catalytic amount) and heated to 200°C
Answers
The dehydration of ethanol to yield ethene
In this process, ethanol is heated with an excess of concentrated sulfuric acid at a temperature of 170°C. The gases produced are passed through a sodium hydroxide solution to remove the carbon dioxide and sulfur dioxide produced from side reactions.
Explanation:
1. Litmus test
Take 2 ml of alcohol and carboxylic acid in a test tube, Put 1 drop of blue litmus in each test tube, the liquid which shows no effect is alcohol whereas the liquid which turns red is a carboxylic acid.
2. Sodium Bicarbonate test
Take a small amount of each compound in a test tube and add to it aqueous solution of NaHCO
3
. The compound which produces brisk effervescence due to the evolution of CO

must be a carboxylic acid whereas which shows no effect is alcohol.
Thus Option A is correct.
