WebExample 4: Reaction of 1,3-Butadiene (CH2=CH-CH=CH2) with HCl. 1,3-Butadiene is a conjugated diene. Two electrophilic addition reactions could occur between 1,3-butadiene and HCl. i) In the first reaction, the chlorine attaches to C-2 and the hydrogen to C-1. This reaction is called 1,2-addition, and its product is 1,2-adduct. WebFor example, in the picture at the beginning of this post we have a couple of electrophilic molecules. The first one has a very polar C=O bond which puts an extremely high partial positive charge (δ+) on carbon. The …

Consider propene, an unsymmetrical alkene. In propene, there is a double bond between C1 and C2 . Carbon-1 has two hydrogens while carbon-1 has one hydrogen. So, when hydrogen bromide attacks the double bond, it prefers to attach itself to carbon-1 which has two hydrogens instead of carbon-2. As a ...
