WebJun 10, 2024 · The tert-butyl group is very bulky, resulting in strong 1,3-diaxial interactions when in the axial position. This makes the A value of the tert-butyl group exceptionally high—about 5 kcal/mol. Compare this with the A values of other groups, almost all of which lie under 2 kcal/mol. Web7 years ago You´re right. It consists of 4 carbon-atoms, so it is butane. It has 2 methyl (one-carbon) groups, so it´s dimethylbutane. And the two methyl groups are at the second and third carbon, so the final name is: 2,3-dimethylbutane ( 9 votes) Show more... grams004 7 …

WebAs a general rule, the most stable chair conformation of a six-membered ring will be that in which the bulkiest groups are in the equatorial position. Exercises Draw the lower energy chair conformations of a) trans-1,2-dimethylcyclohexane, and b) trans-1-isopropyl-3-methylcyclohexane. WebOrganic chemistry. Course: ... The nucleophile cannot squeeze in between the alkyl groups of a 3° substrate to attack the backside of the α carbon. The effect is even worse if the nucleophile itself is bulky. However, a nucleophile like tert-butoxide ion is also a strong base. Therefore, it will go for a β hydrogen in an E2 attack. crystal stairs inc employment
