1.Which of the following compounds are nonpolar?
1) decene
2) decanal
3) 3-methyl-2-decene
4) 1,2-pentanediol
5) cyclohexanol
Select one:
a. 1,2 and 3 only
b. 1 and 2 only
c. 3,4 and 5 only
d. 1,2,3 and 5 only
e. 1 and 3 only
2. Which of the following compounds are polar?
1) 2-butyne
2) propanal
3) propanamide
4) 3-aminopentane
5) 3-heptene
Select one:
a. 2, 3 and 5 only
b. 1, 3 and 5 only
c. 3,4 and 5 only
d. 1,2,4 and 5 only
e. 2, 3 and 4 only

1. For this question I'm tossing up between a and d. I'm pretty confident on 1, 2 and 3 because they are hydrocarbons without any functional groups that can donate protons. I know cyclohexanol has a OH functional group which is very polar but the fact that it's not soluble in water is throwing me off. I would probably go with A at the moment.
2. For this one I'm going with E as 5 is an alkene without any functional groups which means it is nonpolar. This cancels out A-D.
Thanks for the help!
