AI Thread Summary
The discussion revolves around solving a homework problem in Organic Chemistry that involves identifying constitutional isomers of the molecular formula C9H20. The task requires finding isomers that contain one quaternary carbon and one or more ethyl groups, with a total of three isomers to be identified. Participants suggest starting with one ethyl group and determining its placement on the main carbon chain to maintain its classification as ethyl. Emphasis is placed on drawing one isomer first to simplify the process of finding additional isomers. The formula C9H20 is confirmed to represent an alkane. The conversation highlights the importance of structural drawing and systematic exploration in organic chemistry to identify isomers.

I am doing my Organic Chem homework and need help. It asks: Draw and name all constitutional isomers with formula C9H20 which have one quaternary carbon and one or more ethyl groups (there are three). What are they and how do I find them?
 
Chemistry news on Phys.org
Is C9H20 an alkane, alkene or alkyne ? Start with one ethyl group and figure out where you can stick this group on the main chain for it to still be called ethyl. Now fix the main chain by making sure it has a quaternary C.

Start off and draw one isomer, and then you'll find it easier to get more.

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
