of bonds carbon can form

ball and stick

molecular drawing that shows the shape

where are carbons in the line drawing?

line

simplest molecular drawing

nitrogen and oxygen

elements that make a molecule polar

very electronegative

why do oxygen and nitrogen make molecules polar

yes just fewer

can nonpolar molecules have oxygen and nitrogen atoms?

polarities are similar

things will dissolve best when their

polar

is water nonpolar or polar

nonpolar

is oil polar or nonpolar

polar molecules

dissolves well in water

nonpolar molecules

dissolves well in oil

hydrophilic

polar molecule

hydrophobic

nonpolar molecule

water loving

hydrophilic

water fearing

hydrophobic

acid

A substance that increases the hydrogen ion concentration of a solution, lactic acid donate a hydrogen proton to water

base

A substance that decreases the hydrogen ion concentration in a solution, takes a hydrogen proton

<7

the pH of a lactic acid solution

7

pH of an amino acid

7

pH of dopamine

7

pH of lactose

solid lines

covalent bonds are represented by

dotted lines

hydrogen bonds are represented by

polar

type of molecule that will form hydrogen bonds with itself or water

hydroxyl

carboxyl

-COOH

carbonyl

C=O

amino

NH₂

phosphate

-PO₃

sulfhydryl

-SH

methyl

-CH₃

hydroxyl

alcohol, and other things that end in -ol contain; helps dissolve molecules such a sugars, polar, increases solubility

carboxyl

fatty acids and sugars; acidic properties because it is a source of H+, polar

carbonyl

ketones and aldehydes, polar

ketone

double bonds in middle

aldehydes

double bonds on end
