also understan it with explain

Answer 1

HERE'S UR ANSWER

the above reaction is

2.Addition reaction

hydrogen is added to ethene to form ethane

the double bond is removed to allow the addition of hydrogen thus forming ethane.. with a single bond

hope this helps

Answer 2

The reaction $CH_2=CH_2+H_2\rightarrow CH_3-CH_3$ is an example of addition reaction.

Explanation:

a. Substitution reaction : is a type of chemical reaction in which one atom of the reactant gets substituted by another atom.

$CH_3Cl+H_2\rightarrow CH_4+HCl$

b. Addition reaction : is a type of chemical reaction in which one reactant gets added to another reactant to give product

$CH_2=CH_2+H_2\rightarrow CH_3CH_3$

c. Dehydration reaction : is a type of chemical reaction in which water molecule is lost from a reactant.

$CH_3CH_2OH\rightarrow CH_2=CH_2$

d. Oxidation reaction : is a type of chemical reaction in which oxidation number of the reactant gets increased.

$CH_4+O_2\rightarrow CO_2+2H_2O$
