what makes something hydrophobic?
In: 8
Its polarity.
Liquids can be polar or non-polar. Water is a polar liquid because of the difference in “charge” between hydrogen and oxygen. Hydrophobic liquids are non-polar and include oils/hydrocarbons (long chains of carbons singe-bonded to hydrogen)
Plastics/ polymers are hydrophobic because they are largely made up of long hydrocarbon chains which is why rain coats are made of nylon and such.
