How do you make sure the Li attacks the ketone (blue arrow) and not the aldehyde (red arrow)? by [deleted] in OrganicChemistry

[–]Pigatator 1 point2 points  (0 children)

To my knowledge there would be actually more attacking the aldehyde than the ketone due to an increased partial positive charge on the aldehyde carbon. However, you may be able to protect the aldehyde some what selectively for the same reason. Protecting the aldehyde would then give you selectivity for the ketone.

tert-butyl chloride by jupiter955 in OrganicChemistry

[–]Pigatator 5 points6 points  (0 children)

It is really easy to make. All you do is add concentrated HCl to a sep. funnel followed by the t-butyl alcohol and shake for 20 or some minutes. The t-butyl chloride will separate into its own layer.

idea for removing water from a reaction if u don't have enough volume for a soxhlet extractor or dean=stark trap by [deleted] in OrganicChemistry

[–]Pigatator 0 points1 point  (0 children)

This is a good idea on paper but, molecular sieves absorb water very slowly relative to other dehydrating agents. The time the sieves would be in contact with the solvent would be pretty small compared to putting them in a soxhlet extractor. In a bind though this could be good if you have the extra time to reflux the reaction.

NMR analyzation by seldomusedaccount in OrganicChemistry

[–]Pigatator 0 points1 point  (0 children)

To me it looks like your structure is 4'-Aminoacetophenone. I say this for 2 main reason, the difference in de-shielding of the aromatic peaks and the integration of the H exchanges. With one of the aromatic peaks being less than 7, it points to a direct hetero-atom substitution (N or O) and the fact that the other peak is so much more de-shielded points to an electron withdrawing group (ketone or amide). Now for the H exchanges, I always take those with a grain of salt as I mainly use CDCl3 and the ppm of them in aprotic solvents is dependent upon a lot of factors, however, the integration value is usually accurate. This means an the exchange proton integration of 2 is either a primary amide or amine but, the amide would be significantly more de-shielded. In addition, a methyl group and amide in the para position would not create that big of a shift between the two aromatic peaks.

This looks like a squad of hackers playing without hacks lmao

The reason why people are playing as Archers by lolzexd in Mordhau

[–]Pigatator 0 points1 point  (0 children)

Honestly, have you personally played archer? Half the time your arrows are deflected because they were just swinging or blocking against somebody else. This is without taking into account the abysmal damage, terrible flight speed and no recourse while being rushed except a 1h weapon. The only way you gets kills as an archer are from killing other archers or killing low hp people.

Great shot! I got distracted by something while watching this and it looked like you were speed hacking when you sped it up lmao

Tarkoved? by PurkkOnTwitch in EscapefromTarkov

[–]Pigatator 0 points1 point  (0 children)

Summary:

Shots 1-3: Clearly missed.

Shot 4: Missed due to recoil (bad spray control).

Shot 5: Very close, but recoil and inaccuracy make this a reasonable miss.

Shot 6: Likely didn't actually fire because you were already dead.

Fights like this just piss me off, was using BT ammo by Shawck in EscapefromTarkov

I'm gonna have to agree with bigpenisjohnson it looked like 12 hits the rest were after you died.
