What is the correct name for the following l,3-dibromo-3-methylbutane 2,4-dibromo-2-methylbutane 3-methyl-l,3-butyldihalide 2-methyl-2,4-butyldibromide Nomenclature How would you name the compound below? (R)-4-bromohexane (R)-2-bromopentane (S)-4-bromohexane (S)-2-bromopentane Reactions In an SN2 reaction between bromomethane and hydroxide ion, the concentration of bromoethane is tripled and the concentration of hydroxide ion stays of reaction. Stays the same Triples Quadruples Doubles Reaction Rate SN1 In an SN1 reaction between 2-bromo-2-methylpentane and hydroxide ion, when the concentration of hydroxide ion is tripled the rate of reaction Does not change Increases by a factor of 6 Doubles Triples Reaction Rates: SN2 and SN1 If a substitution reaction rate doubles when the concentration of 2-bromo-2-methylbutane is doubled and the concentration of hydroxide ion is doubled, the reaction mechanism is most likely SN1 SN2 Predicting Products When (S)-2-bromo-2-methyloctane is reacted with hydroxide ion in an SN1 reaction the product will be which form of 2-methyl-2-octanol?(the -OH has replaced the -Br) The S isomer The R isomer A racemic mixture Which SN2 reaction below would be the slowest?
