Part B Explain your answer. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. axial In order for a six-membered ring to undergo an E2 reaction, the substituents that are to be eliminated must both be in positions. equatorial When bromine and an adjacent hydrogen are both in axial positions, the large tert-butyl substituent is in an trans position in the cis isomer and in an position in the trans isomer CIS Because a large substituent is more stable in an position than in an position, elimination of the isomer occurs through its more stable chair conformer, whereas elimination of the roccurs through its more sta somer has to occur through its less stable chair conformer. The isomer, therefore, reacts more rapidly in an E2 reaction. reset helpExplanation / Answer
In order a six membered ring to undergo an E2 reaction, the substituent that are to be eliminated must both be in axial positions.
When bromine and an adjascent hydrogen are both in axial positions, the large tert butyl substituent is in an equatorial position in the cis isomer and in an axial position in the trans isomer.
Because the large substituent is more stable in equatorial position that in an axial position, elimination of the trans isomer occurs through its more stable chair conformer, whereas elimination of trans isomer has to occur through its less stable chair conformer. The trans isomer, therefore reacts more rapidly in an E2 reaction.
