Organic Chemistry Exam Overview

The course grade consists of homework, exams, and a final exam totaling 720 points.

Three exams contribute 300 points, making up 41% of the total grade.

Weekly homework assignments total 220 points, accounting for 31% of the course grade.

The final exam is worth 200 points and is cumulative, replacing the lowest semester exam score if it's higher.

Up to 36 points (5%) can be earned through periodic extra credit opportunities.

Dienes with alternating double bonds that react differently than typical alkenes.

A reaction where an electrophile adds to a nucleophile, leading to product formation.

Positively charged intermediates formed at the allylic position in conjugated dienes.

1,2 products form rapidly, while 1,4 products are more stable and form over time.

Kinetic control favors faster-forming products; thermodynamic control favors stable products.

Conjugated dienes show increased stability due to shorter central bonds and lower heats of hydrogenation.

The energy change during the hydrogenation of alkenes and dienes, indicating stability.

The mixing of atomic orbitals to form new hybrid orbitals, explaining diene stability.

A theory that describes the electronic structure of molecules, supporting the stability of conjugated systems.

A key example of a conjugated diene with two double bonds separated by a single bond.

A theory that explains bonding using atomic orbitals and hybridization concepts, impacting diene stability.

A technique that uses ultraviolet light to analyze the absorption of compounds, commonly used with conjugated systems.
