Consider the following reaction:

(a) Draw these condensed formulas as Lew is dot structures. Label the geometry and hybridization of the bold carbons in compounds A and B. Did the hybridization change in the course of the reaction?
(b) Draw the condensed formulas as bond-line structures.
(c) Examine the components of the reaction in light of bond polarity. Using the notation for partial charge separation, δ+ and δ-, indicate, on the bond-line structures, any polar bonds.
(d) This reaction is actually a two-step process: cyanide attack followed by protonation. Depict these processes by using the same "electron pair pushing" technique that we employed for resonance structures in Section 1-5, but now show the flow of electrons for the two steps. Clearly position the beginning (an electron pair) and the end (a positively polarized or charged nucleus) of your arrows.
