Electrophilic addition of cyclohexene
WebAcid-Catalyzed hydration is the addition of water to an alkene which forms an alcohol: The reaction goes through a stepwise mechanism which starts with the protonation of the double bond: The presence of an acid is necessary as the water by itself is a weak acid and cannot protonate the double bond. However, the hydronium ion, formed in acid ... Webusually react with alkenes via an electrophilic addition mechanism involving a bromonium ion intermediate, which leads to anti-addition. Step 1: Reaction of cyclopentene with bromine to form a bromonium ion intermediate (Figure 11-2). Figure 11-2: The first step of bromine addition involves the formation of a bromonium ring intermediate.

WebHydrogenation of Alkenes Reaction Type: Electrophilic Addition Summary • Alkenes can be reduced to alkanes with H2 in the presence of metal catalysts such as Pt, Pd, Ni or Rh. • The two new C-H σ bonds are formed simultaneously from H atoms absorbed into the metal surface. • The reaction is stereospecific giving only the syn addition product. ... WebAlkenes: Halogenation. Halogenation is the addition of halogen atoms to a π‐bond system. For example, the addition of bromine to ethene produces the substituted alkane 1,2‐dibromoethane. The reaction proceeds via a trans addition, but because of the free rotation possible around the single bond of the resulting alkane, a trans product ...
