why is electrophilic addition reaction must happen on double
bond ? Look at this example, the oxygen temporary stabilize the
cyclohexane, but why it has to temporary stabilize cyclohexane
first ? It is not a benzene ring that has extra 150 KJ energy due
to conjugate dienes, And why is oxygen carbocation intermediate
cannot attacked by the nucleophilic chloride ion?

Electrophilic addition to an alkene proceeds via Markovnikov radiochemistry due to the formation of the more stable carbocation intermediate. In the case of conjugated dienes. that is dienes that are separated by one sigma bond, the carbocation that is formed is stabilized additionally by resonance. Addition of the nucleophile to the carbocation intermediate can therefore give two types of products: direct addition to the double bond, also called 1.2-addition. and conjugate addition to the resonance stabilized carbocation.

Identify the nucleophile and the electrophile in the drawing above. 3. Draw a double headed arrow beginning at the nucleophilic lone pair of electrons on one of the oxygen atoms of 2,3-dimethylbutan-2,3-diol and ending on the electrophilic hydrogen of H2SO4. Make sure to push the electrons in the bond between the H and HSO. onto the HSO4 so that...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
