While working in a chemistry laboratory, a student took some zinc granules in a test-tube and added a liquid X to it. A gas Y was produced. When a buring matchstick was brought near the mouth of the test-tube , the gas Y burns with a ' pop' sound, making a little explosion.
(a) What could the liquid X be ?
(b) Name the gas Y.
(c) State two properties of gas Y.

Which gas burns with pop sound ?

A small piece of sodium metal is added to a organic liquid C_2H_6O , taken in a dry test-tube. Bubbles are produced in the test-tube. When a burning match-stick is brought near the mouth of the test-tube, the gas burns with a 'pop' sound, making a little explosion (a) Name the functional group present in the organic liquid. (b) Write the name and formula of an organic liquid having this functional group.

A student took some zinc granules a test tube and added dilute hydrochloric acid to it. A colourless, odourless gas X was evolved .The gas X is:

A pop sound is heard when a lighted match stick is brought near the mouth of a jar. This indicates the release of gas.

What happens when a burning splinter is brought near the mouth of a gas jar containing hydrogen gas?
