Please explain how you identify a compound as being non-polar or polar.
By Anonymous on Thursday, March 2, 2000 - 11:06 am:
Polar compounds possess electronegative functional groups which contain N, O, S, P, halogens, etc. They also may tend to form hydrogen bonds and tend to be soluble in polar solvents. Non-polar compounds contain C, H and other neutral atoms and functional groups. They are less soluble in polar solvents.

You should see a book of Organic Chemistry.
Some rules
1) Check heteroatoms (different from C and H)
2) Check charges
3) Check functional groups (which and how many groups).
4) Acid-base behavior
5) More C and H, less polar
6) more insaturated, more polar
7) More functional groups, more polar
8) Check solubility: "similar dissolve to similar"
7.1) charge compounds like RSO3- ,R4N+ > RCO2-, RNH3+, etc.
7.2) RCOOH > Ar-OH > ROH > ROR > RCHO,R2CO
7.3) R3N > ArNR2 > RCONH
