Question

question 12
why are hydrocarbons considered hydrophobic?
the hydrogen bonds between hydrogen and carbon are nonpolar
the covalent bonds between hydrogen and carbon are nonpolar
hydrocarbons exist as isomers
the covalent bonds between carbon atoms are polar

Explanation:

Hydrocarbons are non - polar due to the non - polar covalent bonds between hydrogen and carbon atoms. Water is polar, and non - polar substances are hydrophobic as they do not interact well with polar water molecules. The other options are incorrect: hydrogen and carbon form covalent (not hydrogen) bonds, isomerism is not related to hydrophobicity here, and carbon - carbon covalent bonds are non - polar.

Answer:

The covalent bonds between hydrogen and carbon are nonpolar
