(a)
Interpretation:
The correct alkene wanted to synthesize pentane molecule has to be identified.
Concept introduction:
Alkanes are the saturated organic compounds which have carbon-carbon single bond.
Alkanes can be prepared from
Catalytic hydrogenation is the process of addition of hydrogen to a compound in the presence of a catalyst. The most common metal catalyst is palladium, which is used as a powder absorbed on charcoal to maximize its surface area. The metal catalyst is required to weaken the very strong
(b)
Interpretation:
The correct alkene wanted to synthesize ethylcyclopentane molecule has to be identified.
Concept introduction:
Alkanes are the unsaturated organic compounds which have carbon-carbon double bond.
Alkanes are the saturated organic compounds which have carbon-carbon single bond.
Alkanes can be prepared from alkenes by various reactions, in which of those reactions catalytic hydrogenation is one of the important reactions.
