Q

what is hydrophilic?

A

loves water

17
Q

what is hydrophilic?

A
  • loves water
  • polar
  • has hydrogen (partially positive), nitrogen and oxygen (partially negative)
18
Q

Whats is hydrophobic?

A

fears water

  • non polar
  • hydrocarbon compounds (O2)
19
Q

what four properties do hydrogen bonds give water?

A
  1. cohesive and adhesion behavior
  2. moderation temperature (meaning it can fluctuate btw temps w/out anything crazy happening)
  3. solid form is less dense
  4. versatile solvent (anything can pretty much dissolve in it)
20
Q

what is cohesion?

A
  • water molecules stick to itself

ex: suface tension

21
Q

what is adhesion?

A

sticks to another polar molecule
