So where did the pentane come from?
So, to clarify. When naming an isomer, you count the carbons in the chain; (exclude the carbons in the branches); and from there, name the compound accordingly?
I had thought it was Butane, because there were 4 carbons; but when I counted the hydrogen atoms there was one missing; i.e. only 9 (if I excluded the hydrogen atoms on the branch, if I were to include them in the computation there would be a total of 12) Butane however is C4H10....so that was the basis of my confusion
