Question 1: Alkanes, Alkenes, and Alkynes Complete the table by labeling each molecule an alkane, alkene, or alkyne.

The labelling of each molecule is listed below:

B.) alkyne

C.) Alkane

D.) alkyne

I.) alkene

Explanation:

In organic chemistry, if an organic compound contains atoms joined only by single covalent bonds, the compound is said to be saturated. The ALKANES are said to be saturated hydrocarbons. For example butane and hexane that is shown in option F and G respectively. If an organic compound contains carbon atoms joined by double or triple covalent bonds, the compound is said to be unsaturated. For example Octene and butyne as seen in option E and H respectively.

Furthermore, hydrocarbons possess8g a set of carbon-carbon double covalent bonds,>C=C<, in their carbon chains form the homologous series called ALKENES while those possessing a set of carbon-carbon triple covalent bond in their carbon chains form the ALKYNE series

From the questions above, a more informative formula known as the structural formula is used to represent the various organic substances. The formula indicates how the atoms are arranged within the molecule of a substance. A structural formula is usually shown as a planar for convenience and does not imply a flat molecule. It shows the actual arrangement of the atoms in space and the angles between the bonds. Therefore options C, D and I are alkane,alkyne and alkene respectively.
