Final answer:
The product of the reaction between CH3CH=CHCH3 and H2 under a platinum catalyst is butane (CH3CH2CH2CH3). This reaction is a hydrogenation reaction where the double bond in the alkene is broken, and hydrogen is added to the resulting carbons.
Step-by-step explanation:
The reaction between CH3CH=CHCH3 (butene) and H2 in the presence of a platinum catalyst is a hydrogenation reaction. This chemical transformation involves the breaking of the double bond in butene, and the addition of two hydrogen atoms from H2. The platinum catalyst facilitates this process. Under high-pressure conditions, the hydrogen atoms are incorporated into the butene molecule, resulting in the formation of butane.
The structural formula of butane is CH3CH2CH2CH3. Hydrogenation reactions are crucial in organic chemistry, particularly in the synthesis of various compounds, as they allow for the saturation of unsaturated hydrocarbons. In this case, the once-unsaturated butene becomes the saturated hydrocarbon butane, illustrating the conversion of a double bond to single bonds.
