Which is more polar Acetaminophen Caffeine Aspirin or Ibuprofen ... Hence, it’s essential to consider electronegativity and molecular structure when deciding if a molecule is polar or nonpolar. This means that the former has a more complex structure, with the addition of an acetyl group making it more polar. The reason for this is surface tension: Surface tension refers to the attraction between molecules on opposite sides of a liquid surface. Aspirin is less polar than caffeine and acetaminophen because of the ether, but it is more polar than ibuprofen. ManCave's Caffeine Shampoo (£9.75 reduced from £13 - yes people, it's on sale) kills two birds with one stone by aiming to tackle both thinning hair and dry and itchy scalps in one fell swoop .

Rank the following compounds according to increasing positive character of the carbon atom. For these reasons, ethylbenzene spent the least time in the stationary phase and the most time in the mobile phase, which is why it traveled the furthest up the plate and had the highest \(R_f\) of the series. How do polar molecules form hydrogen bonds? It’s because caffeine is more soluble in fat than water. As eluent flows over the sample (Figure 2.16b), an equilibrium is established between the sample being adsorbed on the stationary phase and dissolved in the mobile phase. So if you’re trying to determine which substance is more polar in a particular situation, it’s best to consult with a chemist or other expert. Indicate why you think the order is so. b) 2-methylpentane.

Not really sure what math this falls under. Both compounds are able to hydrogen bond to the polar stationary phase (Figure 2.19a+b), so are more strongly attracted to the stationary phase than ethylbenzene, which interacts only through weak London dispersion forces (Figure 2.19c). While both drugs are effective at treating pain and inflammation, naproxen is more polar than aspirin. Aspirin is an acidic compound.
