- Rank the following compounds towards nucleophiles. (1-most reactive - 4- least reactive)3) Explain how and why the reaction below results in the observed regiochemistryand/or stereochemistry.Which of the following compounds will undergo the fastest SN1 reaction? A B IV || C) III E Both I & IV || Br E IV Br
- In both examples below the reactants shown are combined to bring about a nucleophilic substitution (SN1, SN2) and/or elimination (E1, E2) reaction. What is the major reaction that takes place in each case?Copy the given reaction and show the mechanism by supplying the appropriate curved arrows. Also, identify the general type of reaction mechanism (polar or non-polar). For polar reaction mechanisms, label the nucleophile and the electrophile. :0: :0 O.. H. HÖ: Hö:Which of the following would be the worst solvent for an SN2 reaction (slowest rate)? HO.
- b) Explain in detail what characteristics of the alkyl halide influence whether a mechanism will be SN1 or SN2. c) Explain in detail what characteristics of a nucleophile influence whether a reaction will be SN1 or SN2.Rank the following radicals in order from least to most selective.In the reaction given below, which compound is the dienophile? B
- hi please help with: - most likely site of electrophilic aromatic substitution in each - major or minor compounds (explain the reason(s) that you made your choice) - rank the three compounds in increasing order of reactivity (number them as 1,2 and 3 being the most reactive)149) Why is a tertiary alcohol more reactive with hydrogen halides, than secondary alcohols? Because secondary alcohols are smaller and therefore less reactive for the attack of halide nucleophile. Because tertiary alcohols have more hydrogen atoms available for substitution reactions. Because a tertiary alcohol can form a more stable carbocation as an intermediate in the reaction. Only the 1st and the 2nd statements are acceptable.According to the LUMO density map, on which face is the LUMO electronically more exposed to nucleophiles? Based on this data, which face would be more electronically favored? (These questions go hand in hand.)
