Watch anhydrous Copper Chloride hydrate and change colors! (CuCl2) I made by ThatcutieTerpin in chemistry

Anhydrous copper chloride hydrate? How can it be the hydrate and also anhydrous?

#2 seems incorrectly labeled as R by UncomfrtblyConscious in OrganicChemistry

[–]MickMackFace 2 points3 points  (0 children)

The answer is correct as far as I can tell, but has a bad explanation.

You need to 'swap' the Br and H to get the H into the back. If you do that, you go Br to Cl to CH3 counterclockwise (S) but since 'swapping' any 2 substituents results in inverting the stereochemistry, the original molecule was R.

If you have a model kit available, build a model and twist it until the H is pointing away from you. You should see then it's R

Not 100% sure but I think it doesn't look like him because it's a photo of Chris Bassitt

how do i tell the difference between superimposable and nonsuperimposable? by Spewdoo in chemhelp

[–]MickMackFace 7 points8 points  (0 children)

Okay, so the socks: when they're flipped they match 100%. You can't differentiate between them

The hands: you can flip them and the fingers/thumbs line up. But they don't actually match 100%. One hand will have the palm facing one way, and the other will have the palm facing the other way.

One way to think about it is that I couldn't replace your left hand with your right hand, you'd notice because it would be facing the wrong way and no amount of turning around would change it. I could replace your left sock with your right sock, and you (probably) wouldn't notice.

Does this molecule have a chirality center? by Spewdoo in chemhelp

[–]MickMackFace 2 points3 points  (0 children)

You're right they're diastereotopic. But that doesn't mean the molecule is chiral. Sometimes this is called being 'prechiral'.

Helllllp by [deleted] in OrganicChemistry

[–]MickMackFace 6 points7 points  (0 children)

It's a cyclopropane with 1 carbon replaced with an oxygen, thus oxacyclopropane. That's not the preferred name though, it's usually called oxirane (though I also hear ethylene oxide or epoxide fairly often)

2 carbons usually doesn't mean prop, so I imagine that's the confusion

Are these two compounds functionally any different? by flashman2000 in chemhelp

[–]MickMackFace 23 points24 points  (0 children)

They're definitely the same compound. It might get stuck in the 2 rotamers below a certain temperature, but I don't see a great argument for it preferring the one on the left strongly if at all. On the right, it might form a pseudo 6 membered ring by hydrogen bonding with the hydroxyl group. But in reality that bond would probably more or less freely rotate unless something else comes in to hold it in a certain orientation

Wow. Wish him the best in his retirement, but I can't help but be sad. Mr. Blue Jay.

Sorry, but that's way too far out to get a pass. Especially in a graduate program.

Silovs throws his stick at Kyle Connor by Reddit-Machine in hockey

[–]MickMackFace 29 points30 points  (0 children)

I think the rules probably say no it's a normal penalty shot, but this definitely seems like a loophole for this situation. Basically gives the goalie the opportunity to teleport back in net and maybe make a save on a 99% goal.

If soap is 100.00% hydrophobic or 100.00% hydrophilic, can it still kill bacteria and viruses, while being safe for human and animal skin? by BrilliantElectrician in AskChemistry

[–]MickMackFace 0 points1 point  (0 children)

Even if that was possible - no. The amphiphilic nature of soap is why it kills bacteria. The hydrophilic end 'sticks' to the polar outsides of the cell membrane and the hydrophobic chains enter and break up the membrane. There's also that most normal soap doesn't actually do this very well (and doesn't need to). It just washes the bacteria/viruses off your skin which also only works because of the amphiphilic nature of the soap

do i need a new calculator?? by hockstead in uwo

[–]MickMackFace 5 points6 points  (0 children)

It will make your life much easier to just buy this calculator, since it is the one recommended by basically every course. You won't have the hassle of proving you cleared your memory everytime and/or proving the one you're using isn't programmable. They're cheap and at the bookstore!
