Alquenos: Los Hidrocarburos con Doble Enlace

¿Sabías que los alquenos están presentes en muchos productos que usas a diario? Estos compuestos insaturados, también llamados olefinas, tienen al menos un doble enlace en su cadena carbonada y presentan orbitales híbridos sp².

Lo que hace especiales a los alquenos es su enlace pi presente en el doble enlace. Este enlace es relativamente débil, por lo que se rompe fácilmente y hace que estos compuestos sean muy reactivos. Su fórmula molecular general es CnH2n y siempre terminan en -eno.

Reglas de nomenclatura que necesitas dominar:

  • Usa las mismas reglas que los alcanos, pero cambia la terminación "-ano" por "-eno"
  • Cuando hay sustituyentes y doble enlace, el doble enlace tiene prioridad en la numeración
  • Para varios dobles enlaces, usa prefijos como di-, tri-, etc. e indica todas las posiciones

Tip clave: Siempre numera la cadena dando al doble enlace el número más bajo posible, sin importar dónde estén los sustituyentes.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Los alquenos son hidrocarburos súper importantes en química orgánica que vas a encontrar en muchas reacciones. Son compuestos insaturados con al menos un doble enlace, lo que los hace muy reactivos y útiles en la industria.
