In this experiment, you will be looking at nucleophilic substitution reactions on alkyl halides, in which the halogen is replaced with another group. There are two mechanistic pathways for these reactions, $S_N1$ and $S_N2$, which preferentially operate under specific circumstances. 1st attempt Which of the following statements about nucleophilic substitution is INCORRECT? Choose one: OA. Unimolecular nucleophilic substitution ($S_N1$) reaction is a concerted reaction. OB. The $S_N2$ mechanism has a rate that depends on the concentration of both reactants. OC. A tertiary carbocation is more stable than a primary carbocation. OD. A carbocation is an electrophile. See Periodic Table

Theoretically a protein could have an infinite number of ways it can fold. What are some factors that limit the actual shape a protein can take? Select all that apply. Group of answer choices R-groups place limitations on the actual angles phi & psi can take primary structure influences optimal folding in accordance to AA R-group properties the non-rotational nature of the peptide bonds means only trans- or cis- arrangements of the AA are possible proteins are limited to a size of 100 amino acids due to the spatial distribution in a cell
