I attempted some of this but I am clueless as to some of the other stuff. Can you help?

2) Why are the products attached to C3 of 1,4 pentadiene more acidic than the methyl hydrogen atoms of propene?

Maybe you can help me with this one. Are the C3 atoms more acidic because there is more s character involved with the atoms and as the s character increases, the bond length decreases and the carbon becomes more electronegative which ultimately leads to more acidic qualities.

3) Dehydrohalogenation of 1,2-dihalides (with the elimination of two molar equivalents of HX) normally leads to an alkyne rather than to a conjugated diene. However, when 1,2 dibromocyclohexane is dehydrohalogenated, 1,3-cyclohexadiene is produced in good yield. What factor accounts for this?

Well I drew the structures out and I am clueless. I tried researching this scenario on the internet and couldn't find anything that helped. My textbook is no help either.
