Addition reactions are a characteristic property of alkenes and alkynes.
During hydrogenation reaction , the double bond between two carbon atoms breaks and hydrogen is added to each carbon atom.
Alkenes and alkynes on complete hydrogenation gives alkanes.
This reaction is an example of addition reaction.
Answer -- addition

OH Question 20 How many of the following statements are false? The reaction of an alkene with water in the presence of an acid catalyst is called hydration. Most organic compounds are good electrolytes. Oxidation of a tertiary alcohol produces a ketone. Most aldehydes are readily oxidized to become carboxylic acids. Question 20 options:

Catalytic hydrogenation is classified as a 1.2-addition reaction. In this experiment, the hydrogen was added to the double bond of 1-decene in a syn manner, meaning that [Select] both hydrogen atoms are added to the same face of the aliene in 1-pentene both hydrogen atoms are added to the same face of the aliene in 1-decene Syn addition occurs in the type of catalytic hydrogenation because both hydrogen atoms are added by the opposite face of the alkene in 1-decene
