Question

explain the type of reaction with refreence to oxygen and hydrogen . illustrate with examples

Answer 1

Hey there !

You mean reaction between hydrogen and oxygen? Or are you asking for all the reactions oxygen and hydrogen individually undergo?

If it is the first one: hydrogen and oxygen undergo direct combination or combustion forming water. This reaction is also known as oxidation reaction since hydrogen is oxidised by (you guessed it) oxygen.

2H2+O2= 2H2O +∆(heat energy)

If your question belongs to the second category…

Oxygen (quite obvious) takes part in oxidation reactions with most elements or compounds. It can take part in ionic as well as covalent bonds.

Hydrogen is a reducing agent and reduces other compounds. Like oxygen it can form ionic as well as covalent bonds.

Seriously I don't know if it is possible to write down ALL the reactions of hydrogen and oxygen. Both of them are quite reactive and have countless reactions in organic and inorganic chemistry. So, if you really want to know in detail, I'd suggest you to read some high school level chemistry books.

Hope it helps you !
