Multistep reaction mechanisms Group ActivityTreating (S)-2-butanol with HBr results in the following two step reaction: Step 1: CH3CH(OH)CH2CH3 + HBr ⇌ CH3CH(OH2)CH2CH3+ + Br-Step 2: CH3CH(OH2)CH2CH3+ + Br- ⇌ CH3CH(Br)CH2CH3 + H2ODraw a mechanism for each step. Draw structures for all reactants and products, including correct stereochemistry (wedges and dashes). Show all the curved arrows in each step, and label each curved arrow according to whether it represents proton transfer, loss of a leaving group, nucleophilic attack, or carbocation rearrangement.
