Polarity Definition and 159 Threads

hello, i have a question about polarity and SN1 reactions. If we have two solvent mixtures (ex: 2-propanol) but with different concentrations, would the higher concentration solvent be the more polar due to its higher concentration, meaning that there is an increase in number of molecules and...

So, we are just starting ABEL... and I don't quite understand reverse polarity usefullness or application. Here's the extract from my textbook (Wakerly, 3rd ed.): "In this example, the reverse-polarity equation has one less product term than the normal polarity equation (whatever...the...

i cannot get this i have read through texts, and have made probably incorrect postulates of my own on the matter but canot find an easy, or a way at all to calculate spin. (my postulates are limited to the idea that one or two free electron pairs on a simple molecule with one center aom causes...

how do i tell when a molecue is poler... i know its when it was dipole moment that do not cancel each other... but how do i know when a molecule had dipole moments... this one is really stunmping me...nad about all thses questions... no I am not reading them off a list... this is a few moths of...

what is the difference between bond polarity and molecular polarity?

This is a pretty basic polarity question but I'm having a hard time deciding. I had to choose the two major products of methylbenzene with HNO3 and H2SO4. I said that the two major products were O-methylnitrobenzene (1-methyl-2-nitrobenzene) and the other 1-methyl-4-nitrobenzene...

I have time on my hands these days so I bought a Mig/flux welder. I have no idea what I’ll do with it but I always wanted one. The machine allows welding with wire that has a flux core or with a gas “shield. Presumably the gas or flux prevents oxidation of the metal when heated. The...

changing absorptivity Solvent polarity would affect the wavelength of max absorption peak, but how?? and How the solvent affect the absorption coefficient?? is that related sth called Franck-Condon factor?? Also, Flourescent quantum yield also depend on the solvent polarity?? How...

Hey everyone, got a quickie for u. I'm not sure if there is a proper answer for this question, but could ppl give me brief theories to why superconductors repel magnets no matter what polarity they are. thanks for any input!
