### Organic Chemistry Reaction MechanismsBelow are three reaction mechanisms illustrating different types of organic reactions.#### A)**Reaction:**\[ \text{Cyclohexene} + \text{Br}_2 \xrightarrow{\text{MeOH}} \text{Product} \]**Explanation:**- The reactant is cyclohexene, a six-membered ring with one double bond.- The reagent used is bromine (Br₂) in methanol (MeOH).- The product is a brominated cyclohexanol, where a bromine (Br) and a methoxy group (OCH₃) have been added across the double bond of cyclohexene.#### B)**Reaction:**\[ \text{Reactant} + \text{LDA} \rightarrow \text{Product} \]**Explanation:**- The reactant is 1-bromo-2-methylpropane.- The reagent used is lithium diisopropylamide (LDA), a strong base.- The product formed is 2-methyl-1-propene, also known as isobutene. This indicates an elimination reaction where HBr is removed, creating a double bond.#### C)**Reaction:**\[ \text{Reactant} + \text{Br}_2 \rightarrow \text{Product} \]**Explanation:**- The reactant is fluoropropane.- Bromine (Br₂) is added as the reagent.- The product is 1,2-dibromo-3-fluoropropane, where bromine atoms add to the carbon atoms adjacent to the fluorine-substituted carbon.These reaction examples show different types of addition and elimination reactions commonly encountered in organic chemistry. Understanding these mechanisms is crucial for predicting products and designing synthetic pathways in organic synthesis.
