DAT Organic Chemistry Study Review Practice Test. Enantiomer - CORRECT ANSWER Non-superposable mirror images Diastereomer - CORRECT ANSWER Non-mirror images with same chemical formula Meso Compound - CORRECT ANSWER Achiral but has stereocenters Why are axial conformations of large substituents less stable than equatorial conformations? - CORRECT ANSWER 1, 3 diaxial interactions What rings have more ring strain? - CORRECT ANSWER Smaller rings, but not cyclohexane General formu...

What is an epoxide correct answers A three-membered ring that contains oxygen as one of the ring atoms. Lots of ring strain What is the most common way turn an alkene into an epoxide? correct answers By treating it with a proxy acid (m-CPBA) However, this proxy acids are explosive and hard to handle. During the first portion of trans-stilbene experiment, what was the function of NBS? correct answers NBS provided a bromide atom via bromohydration reaction, which created a bromonium ion on t...
