Each measurement gives us another information about a molecule’s overall polarity, but we can never get an absolute value for its polarity from just one method alone. Still, more research is needed before making any definitive conclusions about using caffeine instead of aspirin. Which of the following compounds are chiral? All of these methods have in common: they give one-way measurements of a molecule’s polar character. The one without any methyl groups attached - methyl groups are inductively donating, so when protonated, this nitrogen is least stable. Nitrogen and oxygen are the elements of interest in caffeine for single pairs; uncharged carbons will not have lone pairs. Aspirin’s polarity allows it to dissolve in water, which is also polar. Aspirin is an acidic compound. What are the functional groups present in the following substances (please list/name each one)? b) hexane. VTAC, QTAC and the VCAA have no involvement in or responsibility for any material appearing on this site. In other words, even though they have very similar chemical formulas, these two compounds have very different abilities to attract water molecules and dissolve. However, it’s important to note that this isn’t a hard and fast rule – there are other variables that can affect polarity (including temperature and pH). Dilute violet.

Salicylic acid is also known as 2-hydroxybenzoic acid and 2-carboxyphenol. Acetaminophen. Friedlieb Ferdinand Runge Friedlieb Ferdinand Runge. Both diethyl ether and benzene at first glance appear to be poor choices for extraction because caffeine is more soluble in water than in either solvent (if a gram of caffeine dissolves in \(46 \: \text{mL}\) water, but \(100 \: \text{mL}\) of benzene, caffeine is more soluble in water). Polar molecules typically have one or more highly electronegative atoms surrounded by electron-rich regions. If the electrons are evenly distributed, then the molecule is nonpolar. and to my horror, about 95% of websites say caffeine is more polar than paracetamol. 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.
