Nucleophilic Acyl Substitution Nucleophilic Acyl Substitution is a major reaction for acids and acid derivatives. This is the reaction that converts one derivative into another. The substitution can occur in basic or acidic condition, depending on a derivative. Nucleophilic Acyl Substitution in Basic Conditions-general mechanism NUCLEOPHILIC ATTACK LOSS OF A LEAVING GROUP Nue Nuc Nuc Note: in cases when the nucleophile is neutral (H20, ROH,RNHzl, the mechanism includes one more step: deprotonation of an already attached Nuc: group by another...

+ R products CI HO For the reaction shown above, which of the statements below are true? (Think about the reaction mechanism.) The reaction will be an SN2 mechanism. The product of the reaction will be a carboxxylic acid, RCO2H. Water will act as the electrophile. This will be a one-step reaction with no intermediate. This reaction will proceed via the "up-down-out" mechanism. The reaction will be rapid at room temperature. The intermediate will be a carbocation. There will be...

Please, make the answer clear
and reable.
BrEtOH a OEt Hace H2C Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found to be dependent only upon the concentration of the alkyl halide the reaction is first order. The substitution reaction is thus termed ction is termed E1. These reactions are unimolecular and occur in two steps. The first step is rate-limiting and involves the loss...
