Thank you!

Thanks! But what if you have, say, 2-pentene? Which side is more sterically-hindered (the one with more carbons?)? And what about if you had 4-methyl-2-pentene? Does the methyl group that's farther away have any effect?

How can you predict which product will be in excess if you have asymmetric hydroboration of internal alkynes and alkenes? For example, if I used 9-BBN or something sterically-hindered like R2BH...

Thanks!

Organic Chemistry question! Is 9-BBN too sterically hindered to even react with internal alkynes or alkenes? (to do hydroboration)

May I know whether non-magnetic or magnetic stainless steel cookware leach more? I have looked at the different reasons why some stainless steel is magnetic or not, but it is confusing me whether one leaches more than the other.

Can anybody explain or give me clues to why the kinetic trans effect and the spectrochemical series do not have exact correlations? I know it has something to do with filled p orbitals, but I cannot figure it out.

Could you explain why an H2O that attacks Ni(CN)4 ^(2-) (in square planar) (which has D4h symmetry) at one of the axial sites would have A2u symmetry? I know that the "HOMO" for the p orbital of the H2O would be a p orbital. I also tried to link that electron pair to an irreducible...

Thank you so much by the way!

Yes, please let me know! I am concerned about using the elliptical at the gym. I have heard that "Argenmesh" can block radiation (https://www.amazon.com/dp/B008DXBFYQ/?tag=pfamazon01-20). Some people have reported that they cannot receive phone calls from their cell phone when using Argenmesh to...

Dirty electricity refers to emf radiation. I read about it in this study: http://www.ncbi.nlm.nih.gov/pubmed/18568931

An elliptical machine, shown in this link: http://www.truthaboutabs.com/images/cms/Image/Elliptical.jpg I am wondering where "dirty electricity" is emitted from.

Where does the emf radiation from an elliptical come from? Just the console? I just read an article about dirty "electric pollution," and I was wondering.

How does the Pauli-exclusion principle explain ionization energy trends? Is it just that as you move down the periodic table, the electrons experience repulsion between each other, and thus the atoms get bigger?

Thank you everyone! I realized I had it mixed up, since amino acids exist in +NH3CH3CHCOO- form.
