    DAT DAT Organic Chemistry Hydrogenation Stereochemistry Question | DAT Destroyer | OAT Destroyer | Dr. Jim Romano

    Solution Correct Answer: F — All are true. A) Catalytic hydrogenation proceeds by syn addition, so both hydrogens are delivered from the less hindered face, giving a product in which the two methyl groups are cis. B) The hydrogenation is highly stereoselective because hydrogen approaches...

    What is the total number of isomers with the formula c3h6o that are either cyclic or chiral?

    I get all the isomers. There are four cyclic isomers and seven non-cyclic isomers. According to Khan Academy, the answer for the total number of isomers with the formula c3h6o that are either cyclic or chiral is six. Four of them are the cyclic isomers: (R)-methyloxirane, (S)-methyloxirane...
