Unformatted text preview: best resonance form you can for your answer in (d) - be sure your new resonance form has full octets around each carbon (4 points) f) Even using the extremely powerful bases required to carry out the deprotonations described above, an a l k a n e like propane can NOT be deprotonated in the manner that "A" can. Pick either of the two sites undergoing deprotonation in "A"; specify it (you can use the structure at the top); and explain BRIEFLY what makes that site acidic enough to allow deprotonation. (4 points) alkyne C C C H H C C C H H (2-) H C C C H H H C A C B at C A : carbon is sp-hybridized; greater degree of s-character helps stabilize conjugate base at C B : removal of proton leaves a carbanion which can be stabilized by delocalization with one of the π-βονδσοφτηε αδϕαχενττριπλε βονδ...
