Alkenes have a general formula of CnH2n, n being the number of carbon atoms in its molecular
structure(n > 1). Alkanes are known unsaturated hydrocarbons as it contains a C=C bond in its
structure. The C=C is its functional group. Compared to alkanes, alkenes can undergo a larger
range of chemical reactions such as combustion and various addition reactions( hydrogenation,
addition polymerisation, hydration etc).
Alkynes have a general formula of CnH2n-2, n being the number of carbon atoms in its
molecular structure(n > 1). Alkynes have the highest degree of unsaturation compared to the
alkanes and alkenes. This is due to the presence of carbon-carbon triple bonds in its structure.
The carbon-carbon triple bonds also happen to be the alkyne functional group.

5.0/ 5.0 Points
*Suppose you have a fatty acid that has a 18 carbons in a chain. Suppose also that it is completely
saturated. Will it be a solid or a liquid at room temperature? Explain why according to what we learned
in this lesson. Completely saturated will be solid at room temperature. It'a molecules can be well-packed
in solid state due to they have linear structure.
Model Short Answer: Good. Lipids are discussed in
