Nonpolar substances are ___hydrophobic___ because they have no charges and cannot interact and hydrogen bond with water molecules.
"hydrophobic" = hydro + phobia which is water fearing/dislike
"hydrophilic" = hydro + philien which is love of water
Detergents have both water liking(hydrophilic) "ionic" head and a long water hating(hydrophobic) "nonpolar" tail.
Ionic substances are polar and dissociate as ions in water and are stabilized bu hydrogen bonding with water molecules.
All nonpolar substances are hydrophobic!

hydrophobic..means doesn't like water. Because these substances are nonpolar they won't interact with the water molecule and break apart, so they will not dissolve in water. Hydrophobic is the answer.

Drawing those out shows: A) this would nicely be a keytone, I.e. a C-C(O)-C bond, the place the C(O) is a C=O (double bond). for this reason, the O has 2 lone pair of electrons and can take part in hydrogen bonding with water. B) it incredibly is an aldehyde. This has a C=O bond additionally on the tip of the chain, and could for this reason have 2 lone pairs of electrons with which to take part in hydrogen bonding. C) this would nicely be a halogenoalkane. in spite of the reality that C-Cl is a polar bond, it is not polar adequate to take part in hydrogen bonding. it is going to for this reason be a minimum of partly miscible with water, besides the shown fact that it is going to no longer take part in hydrogen bonding with water. D) this would nicely be a carboxylic acid team. there's a C=O bond in this additionally, meaning that this alkane will take part in hydrogen bonding in water. probably, the C-O-H would desire to take part in hydrogen bonding, besides the shown fact that, in a carboxylic acid the H turns into dissociated interior the water as H+ ions (it is what makes this a carboxylic _acid_ team). The O-H bond does take part in hydrogen bonding in alchols.

hydrophopic
water is polar and polar substances are hydrophillic (like water)
nonpolar substances are hydrophobic (don't like water)

Hydrophobic (means dislike water )
