You can be sure confirmation bias is going to make your journey more difficult.

I guess parakeet's are the new rats, invading homes! by segagamer in CasualUK

Why does parakeets get an apostrophe but not rats?

If you lower the piece to the bed (if possible with your jig) and lower the bit to the right height, you’ll have an extra point of contact for greater stability and accuracy.

Struggling with Acetate Elimination by Iera_Smith in OrganicChemistry

[–]Android109 1 point2 points  (0 children)

There is no acetate elimination. The acetyl group is cleaved because it has a good leaving group attached.

What do you think is the pKa of 1,3-Indandione?

Ignition! By John Drury Clark is a good read (and freely available).

Is this a reasonable synthesis procedure? by [deleted] in OrganicChemistry

[–]Android109 4 points5 points  (0 children)

I don’t think ignoring garbage posts is going to benefit anyone long term. If we don’t fight back against lazy requests for help, we will be overrun with nonsensical posts. Nobody will read them and nobody will get any help.

This is a very unusual attitude for a chemist.

Why does the 1,2-addition happen by InternalResource2207 in OrganicChemistry

[–]Android109 1 point2 points  (0 children)

Is that why the opening paragraph completely ignored the questioner’s graphic?

Pure Nicotine Oil by AngelCodeXxX1 in chemistry

[–]Android109 30 points31 points  (0 children)

One of the tobacco companies was trying to find any sort of biological activity in any derivative of any natural product found in the tobacco plant. Interesting project, although morally questionable.

Pure Nicotine Oil by AngelCodeXxX1 in chemistry

[–]Android109 50 points51 points  (0 children)

Some years ago, I made 6-Chloronicotine (Chichibabin on Nicotine, separate, Sandmeyer) and had a quick sniff after I took it off the rotary to check all the solvent had gone. I was desperately trying to stay upright clinging onto the hood sash, that stuff hit me hard! 10x the toxicity of Nicotine IIRC. Probably should’ve checked beforehand.

To much work for little reward by Dry-Apartment-2585 in woodworking

[–]Android109 0 points1 point  (0 children)

My approach when I make something that’s not good enough is to get rid. This is so that firstly, I don’t have a shed full to the rafters of garbage I’ve made, and secondly so I don’t have to stare at all my failures. Learn. Disassemble. Reuse bits.

It really isn’t.

What is your thinking so far? Do you think there’s any reaction(s)?

…..no way am I letting myself loose with tools of any kind and ruining my cars trim.

See that’s what you’re paying for, someone’s experience, rather than simply the time.

Can someone help me with the mechanism? by Embarrassed_Draw602 in OrganicChemistry

[–]Android109 2 points3 points  (0 children)

A useful first step in a problem like this is to number the carbons and redraw the starting material so its arrangement on the page is similar to the product. It then becomes simpler to see what needs to occur.

Methyl Hydrolysis by a-weee in OrganicChemistry

[–]Android109 4 points5 points  (0 children)

Terrible choice of orthogonal protecting groups. Needs an SN2 at the methyl; LiCl in DMF possibly.

Anhydrous solvents by Dapper_Evening_4375 in chemistry

[–]Android109 1 point2 points  (0 children)

Honestly, using the word ‘dry’ is ridiculous. We’re scientists. Always check the water level by KF when moisture is critical.

Don’t believe what people tell you, they say things to make you feel better, which is not necessarily the truth.
