An organic compound X of molecular formula C2H4O2 gives brisk effervescence with sodium hydrogen carbonate. Give the name and formula of X.
If you take a pinch of sodium hydrogen carbonate powder in a test-tube and add drop-by-drop acetic acid to it, what would you observe immediately? List any two main observations.
On adding NaHCO3 to acetic acid, a gas is evolved which turns lime water milky due to the formation of:
(1) Calcium bicarbonate
(2) Calcium hydroxide
(3) Calcium carbonate
(4) Calcium acetate
Using appropriate catalysts, ethane can be oxidized to an alcohol. Name the alcohol formed when ethane is oxidized.
Draw the structure formula of ethyne.
When sodium hydrogen carbonate is added to ethanoic acid, a gas evolves. Consider the following statements about the gas evolved.
- It turns lime water milky.
- It is evolved with brisk effervescence.
- It has a smell of burning sulfur.
- It is also a by-product of respiration.
Assertion (A): Esterification is a process in which a sweet-smelling substance is produced.
Reason (R): When esters react with sodium hydroxide an alcohol and sodium salt of carboxylic acid are obtained.
A spatula full of sodium carbonate is taken in a test tube and 2 mL of dilute ethanoic acid is added to it.
Write a chemical equation for the reaction.
