Question

Important! Answer these questions before coming to lab. Write the answers in your notebook and on a sheet of paper to turn in at the start of lab. Predictions prior to the experiment: 1. Predict the reactivity of the alkyl halides in the Table with Nal/acetone from most reactive to least reactive. Briefly explain your reasoning. 2. Predict the reactivity of the alkyl halides in the Table with AgNO,/ethanol from most reactive to least reactive. Briefly explain your reasoning.. 3. Which compounds, if any, are there that you would expect to be unreactive under both sets of conditions Briefly explain your reasoning

Answer 1

- lution Reaction with Reaction with Nal /Acetone Alkyl halides undu go SN² substitution Read NaI / Acetone hence the order of Reactivity is - primary halides > Secondary> Tertiary - Bromobutue 2-Bromo butane Ć - CH₂ CH-CH2 - CH2 - CH₂ Br / che -H2-CHBr / eltz-CH-CH2CH/ 2,- Bromo 2-metly Propan cits Alkyl halicles andu go SN Bromo benzene (no Recorating substitution Reaction with AgNO₃ /Ethanol where a Carbocation should be formed Irist on which Reagent will attack . primary haliches < Secondary < Teritiary 1-Bromobutane < 2 - Bromo butane < 2 - Bromo 2-methylpropone No reaction Very Reactive due to ease of formation of Carbocation test due & Bromo benzene do not give to Resonance stabilization of the above two Carbo cation
