El grupo alcohol (-OH) manda sobre el radical metil.

Cadena de 5 carbonos con un doble enlace en el carbono 2.

No hace falta poner el "2" porque en una cadena de 4, la cetona siempre está en una posición equivalente.

"Ejercicios de formulación orgánica 1 bachillerato" represent a foundational pillar in Spanish pre-university science education. They are not isolated memorization tasks but structured problems that teach the logical language of carbon chemistry. Mastery requires understanding priority rules, systematic chain selection, and consistent practice. For students, treating these exercises as puzzles rather than chores transforms organic nomenclature from a dreaded obstacle into a manageable, even enjoyable, skill. For educators, providing progressive, varied problem sets with real-world examples (e.g., naming aspirin or vitamin C) can bridge the gap between abstract rules and tangible science.
