, capillary action - CORRECT ANSWER-occurs because water molecules are are
attracted to charges on inner surfaces of narrow tubular structure such as glass
tubes, drawing water to the sides of the tubes
cohesion - CORRECT ANSWER-inter molecular forces between water molecules
caused by the polar nature of water; responsible for surface tension
enantiomers - CORRECT ANSWER-molecules that share overall structure and
bonding patterns, but differ in how the atoms are three dimensional placed such
that they are mirror images of each other
geometric isomer - CORRECT ANSWER-isomer with similar bonding patterns
differing in the placement of atoms alongside a double covalent bond
hydrocarbon - CORRECT ANSWER-molecule that consists only of carbon and
hydrogen
hydrophillic - CORRECT ANSWER-describes ions or polar molecules that
interact well with other polar molecules such as water
hydrophobic - CORRECT ANSWER-describes uncharged non-polar molecules
that do not interact well with polar molecules such as water
isomers - CORRECT ANSWER-molecules that differ from one another even
though they share the same chemical formula
organic molecule - CORRECT ANSWER-any molecule containing carbon; except
carbon dioxide
