Chapter 13, Problem 60P

Interpretation Introduction

Interpretation:

Three alkenes should be identified which results pentane after treating with $H_2$ in the presence of $Pd$ , by considering the stereoisomers.

Concept Introduction:

Alkenes are hydrocarbon molecules that consist a carbon-carbon double bond which has the general formula of $C_n{H}_{2n}$ . Alkanes are hydrocarbon molecules which do not have any functional group.

Reaction of alkene with $H_2$ in the presence of $Pd$ will form saturated alkanes and the reaction is called as hydrogenation reaction.

Cis-trans isomers are fall under geometric isomerism.

Cis isomers- two different groups are on the same side of the double bond.

Trans isomers- two different groups are on opposite sides of the double bond.
