A mixture of CH4 (methane) and C2H6 (ethane) weighs 68.00 grams and it is burned in with oxygen fuel. The products formed in this reaction are H2O and CO2 and these products weigh 13.00 grams. Find the fraction of methane in the original mixture.
Norborneol synthesis in this manner is stereoselective. So, there are two possible products one endo and one exo. Only one will form, but why aren't there actually four possible products since the alcohol can form on either carbon in the alkene?
