Question

Alkenes can undergo addition reactions, where the C=C bond of the alkene is converted to a C-C bond, and two new single bonds are formed with the constituents of the other reactant. Two examples of addition reactions for the alkene ethene (H2C=CH2) are presented below. H2C=CH2(g) + HCl(g) → CH3CH2Cl(g) + H2O(l) Note that when hydrochloric acid (HCl) reacts with the alkene, both the hydrogen and chlorine atoms form new single bonds with the two carbon atoms. When water (H2O) reacts with the alkene, new single bonds are formed between a hydroxyl group (OH) and carbon and between hydrogen and carbon. Consider the bonds that would form if a pure halogen reacted with an alkene. Predict a product of the addition reaction between (Z)-2-butene (CH3CH=CHCH3) and bromine (Br2), and write the chemical formula for that product. Express your answer as a chemical or condensed structural formula.
