Rearrangen 3. (6) Give the mechanistic symbols (SN1, S 2, El, or E2) that are most consistent with each of the following statements. If none of them apply, write N. More than one symbol may be true for each statement (list all that apply), 1-bromopentane reacts faster than 3-bromo-2,4-dimethylpentane by this/these mechanism(s). Corresponds to the reaction profile at the right. Which mechanism gives a racemic mixture of substitution products?

can someone please explain to me how to tell whether substitution (sn1/sn2) or Elimination (E1/E2) im mostly confused on nucleophile or base strong or weak like is there a step by step that you know thats great for knowing what mechanisms to use ? please please be descriptive . write steps to finish mechanism. and explain nucleophile/base/strong/weak and what goes with what mech.
