Explain the products of an electrophilic addition of hydrogen halides (HCl or HBr) for two asymmetrical alkenes. NOTES
Give me Two different examples and Explain the products of an electrophilic addition of hydrogen halides (HC or HBr) for two asymmetrical alkenes. NOTES.
Electrophilic addition of HBr to alkenes yields a bromoalkane. The reaction begins with an attack on the hydrogen of the electrophilic HBr by the n electrons of the double bond to give a carbocation. This step follows Markovnikov's rule with the electrophilic H atom adding to the sp2 carbon containing the most hydrogens, leading to the formation of the most stable carbocation (1°<2°<3°). If possible, a 1,2-shift of either a neighboring hydride or methyl group can occur prior to the...
Electrophilic addition of HBr to alkenes yields a bromoalkane. The reaction begins with an attack on the hydrogen of the elect HBr by the π electrons of the double bond to give a carbocation. This step follows Markovnikov's rule with the electrophilic H adding to the sp2 carbon containing the most hydrogens, leading to the formation of the most stable carbocation (1° < 2° < 3°). If possible, a 1,2-shift of either a neighboring hydride or methyl group can occur...

E. Just as with isolated alkenes, electrophilic addition of H-X occurs with conjugated dienes. The electron pushing mechanisms are the same. Often, two products are formed: 1,2-addition and 1,4-addition products. For the reaction below, provide a detailed mechanism which explains the formation of the two products. Label each product as 1,2-addition and 1,4-addition. Show all electron movement with arrows and all intermediates. Which product will predominate at -80 °C and at 40 °C. HBr F. Please draw the energy diagram...
