Nomenclature What is the correct name for the following compound? 2,4-dibromo-2-methylbutane 3-methyl-l,3-butyldihalide 2-methyl-2,4-butyldibromide 1,3-dibromo-3-methylbutane How would you name the compound below? (S)-2,2-dihaloheptane (R)-2-bromo-2-chloroheptane (R)-2,2-dihaloheptane (S)-2-bromo-2-chloroheptane Reactions In an SN2 reaction between bromomethane and hydroxide ion, the concentration of bromoethane is doubled and the concentration of hydroxide ion doubles the reate of reaction Quadruples Stays the same Doubles Triples Reaction Rate SN1 In an SN1 reaction between 2-bromo-2-methylpentane is doubled and the concentration of hydroxide ion is tripled the rate of reaction Increases by a factor of 36 Increases by a factor of 2 Increases by a factor of 3 Increases by a factor of 6 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 you react (R)-3-bromohexane with hydroxide ion in SN2 reaction, what is the product (R)-3-hexanol (S)-3-hexanol a racemic mixture of the R and S isomers Steric Effects of SN2 Which SN2 reaction below would be the slowest
