Answer:
To determine the number of equivalents of pyridinium tribromide required to react with 1 equivalent of cyclohexene, we need to examine the balanced chemical equation for the reaction between these two compounds.
The reaction between pyridinium tribromide (C5H5N·Br3) and cyclohexene (C6H10) is an example of a bromination reaction. In this reaction, the double bond in cyclohexene is broken, and a bromine atom is added to each carbon atom involved in the double bond. The resulting product is 1,2-dibromocyclohexane.
The balanced chemical equation for this reaction can be represented as follows:
C6H10 + Br3C5H5N → C6H8Br2 + HBr + HC5H5N
From the balanced equation, we can see that for every 1 equivalent of cyclohexene (C6H10), we require 1 equivalent of pyridinium tribromide (Br3C5H5N). Therefore, the answer to the question is A) 1 equivalent.
In summary, 1 equivalent of pyridinium tribromide is required to react with 1 equivalent of cyclohexene.
