Question

Model B Reac H,C acld H2O acid CH CH CHCH Make an "X through the bonds that are broken in the reactants Use an arrow to mark a) nere stoms are added in the reactants forming new bonds b)Describe what happens in these reactions, including which bonds are broken or formed 2. To what general type of reaction do the reactions of Model B belong? (Circle one) Addition Elimination Rearrangement 3. Are the alkenes in the Model B reactants symmetric? (if you draw a lne through double bond, are both sides the same)? 4 Note the location of the added H in the products. Where is the H added, to the carbon with more hydrogens or to the carbon with less hydrogens? 5 Generaize what determines where the H is added in the reactions of Model B by finishing the statement below in in unsymmetric alkene, H is added to

Explanation / Answer

1. B ) these are simple addition reactions. In the first equation, alwkene bond breaks and a water molecule ( oh- and H + ) attaches to carbon 1 and carbon 2. Similarly ale keen bond is broken up and addition of OH - and H + ions takes place by satisfying the c valency. ( 2) Addtion ( 3) No, both the Alkene in both reactions are not symmetric. ( 4) H is added to the carbon with more hydrogen bonds. ( 5) In unsymmetrical Allene’s, H is added to carbon with more hydrogen’s attached.
