AI Thread Summary
The discussion revolves around a request for assistance in understanding molecular structure based on given names of compounds. The user seeks help with identifying the number of conforming molecules related to a tetrahedral carbon and a specific double bond. Clarification is needed regarding whether to use names from a previous exercise to solve the problem. Participants express willingness to assist but require more details to provide accurate help. The conversation highlights the challenge of determining isomers for the specified compounds.

bonjour ! voici un exercice que je n'ai pas réussi a faire lors de mon dernier contrôle... pourriez vous m'aider pour que je puisse comprendre pour la prochaine fois? je vous remercie beaucoup.

"compte tenu de la présence d'un carbone tétraèdrique et d'une double liaison particulière, expliquer combien de molécules sont conformes aux informations données par le nom fourni pour définir (incomplètement) cette molécule."

je ne sais pas si il faut utiliser les noms des molécules de l'exercice précédent...
si elles sont nécessaires, les voici :
3,5-diéthyl-4-isobutyl-6-méthylnonane
et 1,2-dibromo-3-chloro-5-éthylocta-1,4-diène

I took 5 years of french love and i would be more than happy to help you :smile:, but I'm not 100% clear on what you are asking for. Could you clarify a little bit...by the way, my french was only to the four honors level so its not AP:blushing:. I'll still help as best I can. I also understand your frustration!
 
I believe she is asking for the number of isomers for each compound (but I suspect I'm wrong).

This is a double-post. The other copy is in K-12 homework help.
 
comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
