An important portion of this course is the recognition of essential chemistry functional assorts. These are parts of a molecule, with a specialised structure that functions in a certain way. Not solo are you to learn to recognize the functional groups (a listing tidy sum be found in your textbook or on the back cover of this laboratory manual), but you are alike to learn the physiologic and chemical properties of each of the functional groups canvas in the course. This laboratory exercise will introduce you to ii of these functional groups, alcoholic beverages and phenols, as well as some of their physical and chemical properties.
Alcohols
Although you may be familiar with alcohol as a beverage, the word actu wholey represents an entire classification of organic molecules and not just one substance. Alcohols contain the
(OH (hydroxyl) functional group attached to a saturated hundred. Notice that we did not anticipate this the hydroxide ion, because this group does not act as an bean substance.
Alcohols are classified into three categories: primary (1°), secondary (2°) and ordinal (3°). This classification is based on the number of carbon-containing groups (R( for an alkyl or an aromatic group) attached to the carbon bearing the hydroxyl group. If the carbon bearing the
(OH has one R( group, the molecule is a primary alcohol.
If twain R( groups are attached, it is a secondary alcohol. If three R( groups are attached, the alcohol is tertiary.
I.Physical Properties of Alcohols
The hydroxyl group present in all alcohols is a polar functional group. The polarity of this group allows alcohols to function hydrogen bonds. Small chain alcohols are able to melt with water because of the hydrogen bonding interactions that will occur betwixt the hydroxyl functional group and the water. If the R-group of the alcohol becomes too salient however, the solubility of the alcohol will decrease.
