Whether the same or different product is obtained from the hydrogenation of 1-butene and trans-2-butene is to be determined. Concept introduction: An addition reaction is a reaction in which two molecules react to form one larger molecule. Unsaturated hydrocarbons ( alkenes and alkynes ) have carbon-carbon multiple bonds and thus undergo addition reaction. The hydrogenation reaction is an example of an addition reaction. In the hydrogenation reaction, the hydrogen atoms are added across the double bonds. Alkenes have a double bond between carbon atoms. Due to the presence of a double bond, the rotation about adjacent carbon-carbon atoms is highly restricted. In alkenes, when the two same groups are on the same side of the double bond then is known as cis-isomer and when the two same groups are on the opposite side of the double bond then is known trans-isomer.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
