Question

Jame: . Complete this mechanism for the following substitution reaction. Note: this reaction is balanced. H-Br Н,0 OH -CH3 H20 Step 1: proton transfer Step 2: lose water Step 3: attack the carbocation Br -CH3 . Each reaction above is reversible. In question 1, what effect would adding more HBr have on the equilibrium? Would there be more or less alkyl bromide product present at equilibrium? . Two dehydrations can occur on glycerol, the principle carrier molecule in vaping devices. Provide arrow pushing mechanisms and missing intermediates. Numbering the C atoms may help. он он ОН ОН -H OH OH OH OH -H, OH ОН

Bi formo in slep a attack the alkyl promide product at carboration and forms (Ng is In Step2, there Carbocation, therefore we will get more formation of more stable dortfary there is no possibility of rearrangement. So substituted alleyn bromide only
