Ignore stereochemistry. Ignore byproducts. Nal <arrow_forwardFor each reaction, decide whether the reaction is a redox reaction, acid-base reaction, electrophile- nucleophile, or something else. One can begin to identify the type of reaction by looking to see if oxidation numbers of atoms that take part in the reaction change during the reaction. You will need to draw out the structures. a. If the reaction is considered an acid- base reaction, draw out the full mechanism for the reaction. Be sure to indicate which compound is the acid, base, and conjugate acid and base (where possible). b. If the reaction is considered a redox reaction, be sure to indicate which species are oxidized and which are reduced. c. For every reaction you will need to justify your identification of the type of reaction.arrow_forward

Use wedged and dashed lines to draw the (2S,4R)-2-iodo-4-methoxypentane configuration of 2-iodo-4-methoxypentane in labeled box. b. Draw the product(s) of the nucleophilic addition reaction shown. Make sure to use wedged and dashed lines to clearly show the resulting stereochemistry at each chiral center. Label each chiral center as R or S. If there is more than one possible product, draw one in each box - if not, leave one box blank. c.
