Quick question: Hydrocarbon nomenclature

AI Thread Summary
The parent chain in hydrocarbon nomenclature must always include double or triple bonds, as these functional groups dictate the compound's classification. Alkyl groups are prioritized alphabetically when naming, regardless of their carbon chain length. The longest continuous carbon chain is selected as the parent chain, ensuring that it incorporates any significant functional groups. This approach aligns with standard organic nomenclature rules. Understanding these principles is crucial for accurate hydrocarbon naming.

I just have a quick question about hydrocarbon nomenclature:

When picking the "parent chain", I know that you're supposed to pick the one with the longest carbon chain... does the parent chain always have to have the double/triple bonds? Or can the double/triple bonds be located in a sidechain?

Also, when prioritizing alkyl groups, what has a higher priority - methyl, ethyl, propyl, etc. Or do you just prioritize these straight chain alkyl side groups by alphabetical order?

From what I remember of organic nomenclature the parent must always contain the double or triple. You cannot put as a side-chain. As for alkyl groups you just list them alphabetically.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...

Thread 'How to find the pH of a galvanic cell (MIT OCW problem set)'

This is the final problem in this problem set from MIT OCW. Here is what I did to try to solve it The table cited in the problem is below We can easily spot the two redox couples that are in the electrochemical cell we are given. The hydrogen-based electrode has standard potential zero, and the silver-based electrode has standard potential 0.22. Thus, the hydrogen electrode, with the lower potential, is the reducing agent (ie, it is where oxidation happens) and is the anode. Electrons...
