In Section 12.2, we learned that the Simmons-Smith reaction produces a cyclopropane ring from an alkene.Diiodomethane (CH,I2) is treated with a source of zinc to produce the Simmons-Smith reagent (ICH,ZnI), which reactswith the alkene in a single elementary step. Complete the mechanism below by adding the necessary curved arrows forthis elementary step. Hint: The curved arrow notation is very similar to that for epoxidation involving a peroxyacid.)H,CH2Enantiomer+Simmons-Smith reagent

The question is: "Draw the curved arrow mechanism for the reaction between (2S,3S)-3-methylhexan-2-ol and PCl3. Note the specific instructions for each box. Include nonzero formal charges and lone pairs of electrons on all appropriate atoms" I attached screenshots of the picture of the atoms below. What type of reaction (SN1, E1, SN2, or E2) would the reaction be, and how would these molecules interact? The question asks for multiple steps so I am guessing it is either SN1 or E1, but what is the reaction mechanism?
For the following dehydrohalogenation (E2) reaction, draw the Zaitsev product(s) showing the stereochemistry clearly. If there is more than one organic product, both products can be drawn in the same box.
