Name this reaction: [ mathrm(H)_(3) mathrm(C)-mathrm(CH)-mathrm(CH)=mathrm(CH)_(3) mathrm(CH)_(3) ]

The reaction you have provided is the addition of hydrogen (H₂) to 1-butene (CH₃-CH=CH-CH₃). This reaction is known as hydrogenation.<br /><br />In this reaction, the double bond between the two carbon atoms in 1-butene is broken, and hydrogen atoms are added to the carbons, resulting in the formation of butane (CH₃-CH₂-CH₂-CH₃).<br /><br />The balanced chemical equation for this reaction is:<br /><br />CH₃-CH=CH-CH₃ + H₂ → CH₃-CH₂-CH₂-CH₃<br /><br />This reaction is an example of an addition reaction, where a molecule is added to a double bond or triple bond, resulting in the formation of a single bond. In this case, the addition of hydrogen atoms to the double bond in 1-butene results in the formation of a saturated hydrocarbon, butane.
