Chemistry - GOC Question with Solution | TestHub
Which of the following option is correct?
Options:(select one or more)
Answer:
Solution:
(A) % Enol Content: Correct; less steric hindrance and optimal geometry in the first cyclic dicarbonyl structure better facilitate stable enolization and extended conjugation.
(B) Boiling Point: Correct; as molecular branching increases from straight-chain to tert-butyl bromide, the surface area decreases, weakening the intermolecular van der Waals forces and lowering the boiling point.
(C) Carbocation Stability: Correct; the para-methyl group stabilizes the benzyl carbocation more effectively through stronger hyperconjugation () than the para-isopropyl group ().
(D) Alkene Stability: Incorrect; alkene stability increases primarily with the number of alkylating -hydrogens, meaning the final tri-substituted alkene () is significantly more stable than the others.
