The Molecule Paraffin Has the Formula C₂₀H₄₄

Question

The molecule paraffin has the formula C20H44.What does that tell you about the molecule?
A)It is a protein
B)It is hydrophobic
C)It is a nucleic acid
D)It is polar

Accepted Answer

The presence of many carbon and hydrogen atoms in the formula indicates that this molecule is likely a long chain of hydrocarbons. Hydrocarbons are nonpolar, and therefore hydrophobic, meaning they do not mix well with water. Paraffin is a commonly used hydrophobic substance, such as in candles and as a barrier in cosmetics to limit water evaporation from the skin.
