Question
Match each principle in the left-hand column to the best description in the right-hand column. Each letter is only used once Ozonolysis The reaction mechanism for dehydration of alcohols is exactly the same, but in the opposite direction for the hydration of alkenes oxidative addition Addition of hydrogen halides across a double bond so that hydrogen adds to the least substituted carbon and the halide to the most substituted carbon. dehydrohalogentaion Explains why 1 -bromopropane is the major product after treatment with HBr. Dehydration of alcohols favors the most substituted alkenes. Conversion of alkene carbons to provide two separate carbonyl functional groups. Donation of electron density from a co-planar (periplanar) o-bond into an empty p-orbital of a carbocation. Preferential reaction at a single site of one functional group over other sites that could undergo the same reaction. anti addition Responsible for the isolation of 2-mcthyl-2-butcne from the dehydration of 3-methylbutan-l-ol.Explanation / Answer
(e) : Ozonolysis: Alkenes are cleaved by ozone to form two carbonyl groups.
(a):Dehydrohalogenation: dehydration of alcohols and dehyrohalogenation of alkyl halides are both elimination reactions with similar mechanisms and have an opposite mechanism to that of hydration of alkenes.
(c) peroxide effect: This is an anti markovnikov addition of HBr.
(g) regioselectivity: Prefering one direction of chemical bond making over all the others.
(f) hyperconjugation Donation of a sigma bond from an alkyl group to a carbocation to stabilize it.
(j) anti addition: Halides add to the opposite sides of the double bond giving trans products.
(b) Markovnikov addition: H adds to the carbon with the more hydrogens and halogen adds to the carbon with less hydrogen.
(d) Methyl and hydride shift: Responsible for rearrangements in dehydration, to produce the most substituted alkenes.
(h) dehydrogenation: Is involved in the dehydration of alcohols.
(i) oxidative addition: Alkyl halides undergo oxidative addition.
