Question

Classify the reaction below as an oxidation, a reduction, or neither. 
cis-pent-2-ene → pentane

Quizplus · Accepted Answer

In the given reaction, cis-pent-2-ene gains four hydrogen atoms to form pentane. This means that the double bond between carbon 2 and 3 of cis-pent-2-ene has been broken and carbon 2 has gained two hydrogen atoms while carbon 3 has gained two hydrogen atoms. Therefore, the carbon at position 2 is reduced, and the reaction itself is a reduction.
