An alkane with the formula c6h14 can be prepared by hydrogenation of either of two precursor alkenes having the formula c6h12. write the structure of this alkane, give its iupac name, and show the reactions.

Hydrogenation reactions are those reactions in which Hydrogen molecule is added to the double bond or triple bonds of unsaturated compounds to convert then into saturated compounds with all single bonds in the presence of catalysts like Nickle, Platinum, Palladium e.t.c.

Below three different reactions are given in which the starting materials (Alkenes) have molecular formula C₆H₁₂ and the final product in all three reactions is the formation of same Alkane with the formula of C₆H₁₄.

Remember that the three starting materials are isomers of each other. Such isomers are called as position isomers because they only differ in the position of double bond across the carbon chain.

b is the correct

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
