Below is the SN2 reaction between (S)-2-chlorobutane and cyanide (CN). In the first box, draw the curved arrows to reflect electron movements. In the second box, add the organic product (the inorganic side product is already shown). In both boxes, add all lone pairs of electrons and nonzero formal charges. Box 1: add curved arrows, all lone pairs, and correct non zero formal charges. Box 2: add the missing organic product, lone pairs to the organic and inorganic product, and non zero formal charges H3
