Consider the reaction of cis-2-butene with $\mathrm{H}_{2}$ (in the presence of a catalyst).
(a) Draw the structure and give the name of the reaction product. Is this reaction product chiral?
(b) Draw an isomer of the reaction product.

Key Concepts

Chirality

Chirality is the property of a molecule having a non-superimposable mirror image, usually due to the presence of a chiral center (an atom attached to four different groups). After hydrogenation, if no new stereocenters are generated, the resulting saturated molecule is achiral.

Isomerism in Organic Compounds

Isomerism refers to the existence of compounds that share the same molecular formula but have different structural arrangements or spatial orientations of atoms. In organic saturated compounds, constitutional isomers (or structural isomers) differ in the connectivity of their atoms, as seen in the differences between straight-chain and branched isomers.

Catalytic Hydrogenation

Catalytic hydrogenation is a reaction where molecular hydrogen (H?) is added to one or more unsaturated bonds, such as carbon-carbon double bonds, in the presence of a catalyst. This process converts unsaturated compounds into saturated ones, typically proceeding through a syn addition mechanism on the alkene surface.

Alkene Stereochemistry

Alkene stereochemistry involves the spatial arrangement of substituents around the double bond, classified as cis or trans according to whether similar groups lie on the same or opposite sides. While cis-trans isomerism is significant in the starting material (cis-2-butene), the addition of hydrogen removes the double bond, eliminating this stereochemical distinction in the product.
