Sarah wants to know which brand of nail polish lasts the longest without chipping. she buys 4 types of nail polish – essie (which she normally uses,) butter, opi, and sally hansen. every sunday for 4 weeks she paints her nails with a different brand of polish and records how many days she lasts before she gets her first chip. she makes sure to use the same bottom coat and top coat with each type of polish, and she makes sure to do the same weekly routine each week so that her nails aren't getting treated more roughly different weeks.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20
