Question

1. Select the appropriate labels for the species in the following substitution reaction:

A. B .C.

Choose the following option

Select one:

Rate =  k [R-Br]

Rate =  k [HO]

Rate =  k [R-Br] [HO]

Rate =  k [HO]2

Rate =  k [R-Br]2

3. If the following reaction proceeds via an SN2 mechanism, whats the correct curly arrow diagram for the FIRST step of the process?

[Hint: youre being asked about the FIRST step; the overall reaction may require only a single step, or it may require more than one step.]

1. Select the appropriate labels for the species in the following substitution reaction: Select one: Rate = k [R-Br] Rate = k [HO] Rate = k [R-Br] [HO] Rate = k [HO]2 Rate = k [R-Br]2 3. If the following reaction proceeds via an SN2 mechanism, what's the correct curly arrow diagram for the FIRST step of the process? [Hint: you're being asked about the FIRST step; the overall reaction may require only a single step, or it may require more than one step.] Choose? Electrophile Nucleophile Leaving group 2. If the following reaction proceeds via an SN1 mechanism, what is the rate equation? A. B .C. Choose the following option

Explanation / Answer

Ans -1

A- Electrophile

B- Nucleophile

C- Leaving Group

Ans -2 Rate= K[R-Br]

Ans-3

4th curly arrow diagram is correct. In an SN2 reaction first the incoming nucleophine attacks from back and then the leaving group leaves in from a direction oppostie to incoming nucleophile.
