Ethyl or methyl?
If you have pentane, from each side at the second position a side chain, once ethyl once methyl
Where do I start counting?

I need help with this physics problem?
ByMia1307
Hi, I need help with a task: Hans builds a tower from 5 wooden cubes (edge length 5 cm, density 0.7 g per cm3). b) The top die falls back down from the tower. At what speed does it fall to the table? I need b and I already have the bill from b but…
Why is the equivalence point shifted into the basic range when titrating a weak acid with a strong base?
Sometimes a weak base is formed (e.g. sodium acetate salt in acetic acid with sodium hydroxide). Is this always the case?
Why is there alcohol in hot dog bread?
I happened to see it on the label in bold, big letters… But the ingredients didn't mention alcohol anywhere, and I can't taste any of it. Can someone please explain this to me? I don't drink alcohol at all and don't plan to.
Why is ethanol polar?
ByMaria597
Hello! I'm currently learning chemistry and I'm stuck on the topic of miscibility of alkanes. Ethanol consists of an OH bond, which is therefore polar. I know this is due to its electronegativity. But doesn't ethanol consist primarily of CH bonds, which are nonpolar and therefore form van der Waals forces? Shouldn't it then be…
Glass shattered?
Today my mobile phone glass (back) is completely shattered even though I have a case around it, well, it must have landed wrong or something In any case, there were really fine glass particles on the side of my phone. I was so scared the whole time that I would inhale some of it as…
2-ethylpentane is no longer a pentane.
what you do not say
Oh, you mean, if you substantiate n-pentan. Yeah, I could have come to that.
And the wrong answer
Thank you.
No. Then the remainder in alphabetical order gets the smaller loedges. 2-butyl-3-methylbutanedioic acid, 2-methyl-3-propylbutanedioic acid.
You don’t have Ethy anymore. But if you’re talking about the priorities, then the biggest rest comes first if anything else is the same.
Yeah, right. Thank you.
and the same scenario with hexan?
First erhyl or first methyl?
Ne, have to count from the other direction, as smaller numbers. Then 2.4 would not be 3.5.
So 3,5-dimethylhexane?
Okay, so, you don’t know if you’re supposed to call the mole of 2-ethyl-4-methylpentane or 4-ethyl-2-methylpentane. The names are both wrong. For an ethyl on 2. (or even 4.) It also means that your longest chain can’t be a Pentan. It must be a hexane.
I know that no real pentane molecule anymore I used the name for the stem
And what about the methyl radical?
Don’t be so rude. Besides, he’s right…
At the end of the ethyl side chain is C1.
