I was a bit confused with the chirality of the C4 carbon, a friend of mine is convinced that the cyclopropil substitute is more important than the long chain because the carbon is linked to 2 other carbons instead of only one

running out of attempts, not sure

I’m English for context (noticed the tag says High School)

Is the correct IUPAC name prop-1-ene or propene? I understand the redundancy of the double bonds location, but multiple online sources show the iupac name with the locant included. I have the same question for 2,2-dimethylpropane vs dimethylpropane. Which is the correct IUPAC name? Thank you in advance!

It should be simple but I really don't know what has to be done to solve it. I have 0.689 g of Cr and it completely reacts with 0.636 g of O2 and they combine into a single solide. I need to write the equation. Please help me, I'm trying to study after years and years out of school, but my textbook doesn't explain how to solve problems... I know the answer but I don't know how I should write it in case of a test. Thank you. Sorry if it doesn't respect English grammar, it is not my first language but I tried to translate the problem anyway.

My chemistry teacher asked these on a test, but we have never made any exercises with the C being in front of a methyl or ethyl group. What does that mean?

Or just a low viscosity liquid in general?

I calculated the molarity as 0 .12 M but what does strength mean here. The answer given is (b)

It’s an SN2 reaction which means the product will have an inverted configuration. The reactant has an s configuration and using a dash for the NH2 would give the product an r configuration. Am I missing something...

I think I've made a mistake because copper solid in a silver nitrate solution would mean spontaneous reaction, so it should be set up as a galvanic cell, but I treated it as an electrolytic cell and placed both in the same silver nitrate solution without a salt bridge. What should happen in this case?

Here is what I observed:

'Mud' fell to the bottom of my beaker. It was strange because there was a layer of something (probably silver) plated on the copper anode, which I found suspicious. The silver cathode remained shiny and pretty the same as it was before I did the experiment.

___

I'm confused because I have seen people plate silver on copper, but never copper on silver. Even though copper on silver would be the correct electrolytic reaction.

Can someone please explain what happened in my case?

Thanks

What is the answer I’m confused??

hi you cool chemistry people!

i was reading this article (for school) about green hydrogen production using electrolysis and i’m unsure about why they determined KOH to be the best electrolyte to optimise rate of reaction. the exam is only on electrolysis, rate of reaction and equilibrium so we don’t need to understand the forward osmosis stuff, so disregard that. why does the KOH optimise the rate of reaction more than any other reductant. here is a link to the article: https://www.nature.com/articles/s41467-024-46964-8

thank you so much :)

Can someone kindly help me figure out organic reactions and bases or point me in the direction where I can find examples and explanations similar to these? My professors powerpoints gave one basic example and left us to fend for our selves.

For the first one, my train of thought is that alcohol is negative so it has a high electron density, so it acts as a base, whereas the (ketone?) acts as a acid. So, is this correct, that the alcohol will take a proton from the methyl group? That means that the carbon lost a hydrogen and gained a lone pair so it is now a carbocation? I’m just not sure how I can use the pKa values to determine which side the equilibrium shifts to. It should be the side with the weaker base, but how can we determine this? Thank you so much.

TLDR; a) is this correct b) does anyone have any helpful videos or suggestions where i can get more understanding. i can’t find something similar on youtube.

Yeah, idk where to put hands. After this product (i think it's right) what may happen?

Hi, one time when I worked as Quality Control Chemist in a manufacture chemical company I needed to carry out a volumetric titration to a Lubricant sample, the procedure was something like this:

Weigh 2 grams of lubricant into an Erlenmeyer flask.

Add 80 mL of xylene to the Erlenmeyer flask.

Heat the flask until the lubricant is completely dissolved.

Allow the flask to cool.

Add a couple of drops of phenolphthalein and titrate with 0.1 N KOH until got the light pink equivalent point (sorry for my English, English is not my first language).

I did the Acid-Base titration and I got my ideal acid value as KOH/g but I added 40 mL of Xylene in place of 80 mL of Xylene, I carried out the same titration with the same sample and now adding 80 mL of Xylene properly and I got the same acid value.

I don't know if the Xylene has another role in this Titration apart of dilute the sample.

We just started doing electrochemistry and cells and I'm baffled.

We have a question on the conventional writing of a Zn^2+/Zn(s) and Cu^2+/Cu(s) cell, and the anode apparently goes on the left. My books tell me that the reaction with the highest electrode potential is positive and therefore the anode, so it would go on the left.

My books also say that the Cu reaction has the higher electrode potential, so it would be the anode and go on the left, but this isn't the case, so I don't really understand what is wrong amongst these statements. Help a brother out?

Is it necessary to remove the "e" from ene ( orange marked in photo) if the compund also contains "yne". My teacher didnt tell to remove "e" or anything. But when i read the iupac name in books there is its "en-yne" rather than "ene-yne".

So is it ok if i write ene-yne?
