4. Complete the following reactions (use curved arrows to show the flow of electron pairs in each reaction) and label the reagent that acts as a nucleophile and the one that acts as electrophile, if any. A CH3CO2H + OH- B CH3CO2 + CH3NH3* – C CH3CH2OH + HCI D CH3CH2Li + CH3CI – E NH3 + AICI: obsoni moto oblastomatolls F ~ N 0-0-0 ВЕСІ
Use curved arrows to show the movement of electrons in the following reaction steps. (Hint: Look at the reactants and look at the products and then draw the arrows to convert the reactants to products.) Part A Draw electron flow arrows. Electron flow arrows should start on an atom or a bond and should end on an atom, bond, or location where a new bond should be created. D ®, H: 6 mm 0 + i \' z o LOH...
4. Add curved arrows to show the movement of electrons in each of the following reactions. Note that you should draw in any lone pairs that are relevant to the mechanism. (a) OCH2 CH3 -O. H + (b) CH3 IN OH CH2 + +
Draw curved arrows to show the movement of electrons in each of the reactions in the left box. Then, draw the missing organic product in the right box for each. H3 + NH3 + CH4

Show curved arrows to indicate the flow of electrons. Show
appropriate charges and/or lone electron pairs to initiate electron
movement. Show any bonds that must be explicitly drawn when
transferring bonding electrons.
