Nettet16. mai 2008 · The most substitued carbon is the carbon with the most things substituted for hydrogen. So methane is degree 0. n-Butane has 2 primary carbons and 2 secondary carbons. (The ones on the ends are the primary carbons) Isobutane has 3 primary carbons and 1 tertiary carbon (the center one). neo-Pentane has 4 primary carbons and one … NettetThe difference in regioselectivity arises because of the different process used to arrive at the enol/enolate in the acidic and basic cases. In the acidic case, 1) the carbonyl oxygen is protonated and then 2) a proton is removed from the alpha carbon to form the enol. See here for a good picture of this mechanism.
