How to prepare methanal from methane?
Answers
Procedure : Anhydrous sodium acetate and soda lime are taken in the ratio 1:3 by weight and are mixed immediately. The intimate mixture of sodium acetate and soda lime thus prepared is taken in a dry hard glass test tube fited with a cork through which a delivery tube passes. The hard glass test tube is Now heated strongly when methane is evolved .The first part of the evolved gas is allowed to escape to remove the air inside the test tube . Methane thus produced is collected in a gas jar by the downward displacement of water.

An aldehyde is a compound containing a functional group with the structure −CHO.
And its prefix is -al.
When oxygen gas (O2) is added to methane, then methanal and water is produced.
CH4 + O2 → HCHO + H20
Where HCHO is methanal.
Its structure is
