Question

Draw the product formed when cyclohexene is reacted with H2 in the presence of Pt.

Note: If adding hydrogen atoms to a carbon atom, include all hydrogen atoms bonded to the carbon atom. Otherwise, the answer will be marked as incorrect.

Answer 1

Concepts and reason

The product formed as a result of the reaction of cyclohexene with ${{\rm{H}}_{\rm{2}}}$ in presence of ${\rm{Pt}}$ (platinum) can be described on the basis of catalytic hydrogenation. Catalytic hydrogenation is defined as the process of hydrogen addition in the presence of a catalyst, which in this case is platinum.

Fundamentals

Cyclohexene (alkene) is a hydrocarbon molecule represented by the chemical formula, ${{\rm{C}}_{\rm{6}}}{{\rm{H}}_{{\rm{10}}}}$ . It consists of a double bond. During the hydrogenation reaction, the alkene undergoes a chemical reaction to give alkane as the product.

The first step in order to derive the product is to draw the chemical structure of cyclohexene and identify the double bond present in it. The structure of the cyclohexene has been drawn as follows:

The final product can be derived by replacing the double bond with the single bond and satisfying all the valences of the carbon atom. The final product structure has been drawn below:

Ans:

The structure of the cyclohexane thus, formed has been shown as follows with all the hydrogen atoms:
