For the chiral center example, why does the CH2 have 2 signal but CH3 have 1 signal? I assumed that since each H in CH2 are at a different distance from OH, there are 2 different signals. However, Wouldn't the same logic also apply to the CH3?
For the chiral example this may not be the best way of thinking about it in terms of how correct it is but think of that chiral carbon and the ch2 group next to it in a Newman structure. Due to the chirality centers being present on the carbon with the hydroxy group it will have gauche interaction with the hydrogen that is facing the same way as the hydroxy. The methyl ch3 group at the end that is next to the carbon are unaffected by this because the sigma bond between carbons can spin and they will be impossible to tell the difference in terms of chemical environment. But the ch2 does get affected by the hydroxy because while one is affected the other one is being affected by gauche interaction. It is easier to see in a molecular model than 2d video
I would think it should be 3 because in a cyclohexylbromide you have a line of symmetry. Think of the bromide ion on the top, then the immediate hydrogens adjacent to it on either side (ortho position) would have one environment, the hydrogens on the meta position will also have one hydrogen enviornment, and the last hydrogen on the para position will be unique, so it has one hydrogen environment. When you count them up, you get 3! Hope this helps
Organic Chemistry on Khan Academy: Carbon can form covalent bonds with itself and other elements to create a mind-boggling array of structures. In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them. We will also think about how those reactions are occurring on a molecular level with reaction mechanisms. Simply put, organic chemistry is like building with molecular Legos. Let's make some beautiful organic molecules!
I know im uber late on this comment, but the reason its a chiral center is because the chains on either side of the carbon thats attached to the hydroxyl group are different. Looking at the chiral center carbon, the right side of it has an ethyl group, while the left side has a methyl group, therefore both sides are different. If both sides were say a methyl group or an ethyl group, then it wouldnt be a chiral center.
Pffft, that's shinobi 101, think you skipped a bit far ahead. you need at least raikage credentials to be here, go back to trying to master chidori LOL childs play
