AI Thread Summary
To determine if chemicals like beta-sitosterol, methyl cinnamate, and others are polar or nonpolar, examining their chemical structures and functional groups is essential. Identifying major functional groups, such as esters in methyl cinnamate, can provide insights into their polarity. Websites that offer chemical diagrams can aid in this analysis, allowing for a visual assessment of the compounds. Solubility is another key factor; the principle "like dissolves like" can be applied to classify polarity. Understanding these concepts will help in determining the polar or nonpolar nature of the listed chemicals.

I need to determine whether these certain chemicals are polar or not:
Beta- sitosterol
Methyl cinnamate
Lapachol
Ethyl p-hydroxy cinnamate
Betulic acid
3,4,5- trihydroxy-7-methoxy flavone
Veratric acid
p-anixic acid


Many of them are difficult, If there is a website that could help in determing whether these compounds are polar or not I would appreciate it. :confused:

In order to figure out if things are polar or not, I like to look at diagrams...google your compounds individually and I'm sure you'll find a chemical structure.

For example, here's one for methyl cinnamate: http://www.thegoodscentscompany.com/data/rw1417571.html

Now that you know what it looks like, identify the major functional groups and try to figure out the properties of each. For methyl cinnamate, you have and ester...is an ester polar or non-polar. After you figure out functional groups, another property you can use to classify polarity is solubility. As a rule of thumb, like dissolves like. Hope that helps!
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
