Which of the following are properties of hydrocarbons?
A
Hydrophobic, polar, charged
B
Hydrophilic, good source of stored energy, consisting primarily of carbon and hydrogen
C
Hydrophilic, containing numerous carboxyl groups, nonpolar
D
Hydrophobic, nonpolar, good source of stored energy
검증된 단계별 안내1
Understand that hydrocarbons are organic compounds consisting entirely of hydrogen and carbon atoms.
Recognize that hydrocarbons are generally nonpolar because the carbon-hydrogen bonds have similar electronegativities, leading to an even distribution of charge.
Identify that nonpolar molecules, like hydrocarbons, are hydrophobic, meaning they do not mix well with water.
Acknowledge that hydrocarbons can be a good source of stored energy due to the high energy content of the carbon-hydrogen bonds.
Conclude that the properties of hydrocarbons include being hydrophobic, nonpolar, and a good source of stored energy.
