In addition to running aspartic acid, phenylalanine, aspartame and hydrolyzed aspartame, let's assume that you also ran leucine on your tlc plate in this lab. would you expect leucine to travel farther than or less than aspartic acid, and why?
a. leucine is nonpolar, thus it should travel farther than aspartc acid on my tlc plate
b. leucine is polar, thus i should travel less than aspartic acid on my tlc plate
c. leucine is polar, thus it should travel farther than aspartic acid on my tlc plate
d. leucine is nonpolar, thus should travel less than aspartic acid on my tlc plate.

i wish i could but this one is weird give me abc and i can solve it.

sure im new too!

explanation:

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

the answer is c.the valence of the atoms combine .
