Questions about nucleophile.. I heard that, down a column, it's good nucleophile but.. generally, strong base is strong Nu (exept for solvent issue) and 'As' (from AsH3) is more polarizable than 'P' (from PH3) thus, i think, As is to weak base(since it is stable) and P is more strong.. but it's not. why?
How can you tell what is a weak/strong nucleophile and a weak/strong base to determine what mechanism you use (SN1, SN2, E1, E2)? 3. Draw a structural formula for the major organic product(s) of each reaction and specify the mechanism by which each product is formed (SNI, SN2, El, or E2).

1. Sketeh the energy diagram for a spontaneous second order reaction. Clearly label all axis, the rate limiting step, transition state(a), intermediate(s), and enthalpy change. (4pta) Draw the mechanism given the following reaction: 2. (4pta) (3pts) Rank the following in decreasing strength (1-strongest) of the C-halogen bond: 3. 4. Of all halogens we talked about in lecture, which halogen is considered the best leaving group? Explain why (give 2 reasons). (4pts) 5. Rank the following in decreasing nucleophile quality (1-strongest)?...
Why is NC- a good nucleophile? and why is it a weak base?
In the face of strong evidence, why do you think that managed behavioral health has been slow to develop and has developed as a niche industry by carving out behavioral health and managing it separately? What are the reasons for this, and what alternative strategies might be considered?
How can you tell if a reactant, like the NaOH, is a strong/weak nucleophile or base to determine what mechanism you use? The picture provided has the correct answers. I just don't understand how to get to them. 3. Draw a structural formula for the major organic product(s) of each reaction and specify the mechanism by which each product is formed (SN1, S2, E, or E2).
