Carbon (Alcohol part1)

Carbon compounds called organic compounds will also be discussed on this occasion just a simple organic compounds by grouping classes based on functional groups which have been discussed earlier. Based on the functional groups of organic compounds are grouped into six, namely, alcohol, alkoxy, Alkanal, Alkanon, alkanoic acids and alkyl alkanoic. In detail the differences of each group are as follows:

Alcohol

1. General formula
Compounds alcohol or alkanol alkane compounds can be said that one of his H atom is replaced by an-OH (hydroxyl). So as shown in Table 1 are alcohol compound of general formula R-OH wherein R is an alkyl group. For this class of compounds of general formula can also be written alcohols CnH2n +1 - OH
Example:

Table 1

Alkyl and alcohol molecular formula

2. Nomenclature

Naming alcohols principle there are two ways:

1) The IUPAC rules that using the name alkananya compounds by replacing akiran "ana" in the alkane becomes "anol" in alcohol.

2) With Trivial system is by mentioning the name of alkyl group followed by the word alcohol.

Example:

Table 2

NAMING EXAMPLE OF ALCOHOL

For compounds of structural formula branched alcohols with naming rules are as follows:

a. Set the main chain by choosing the most long row of C binding-OH functional group, then name the name of the corresponding alcohol. (See table 2)

b. Numbering in the main chain starting from the end that gives the smallest number of atoms that bind to the C-OH groups. The next step is equal to the naming of compounds - hydrocarbons (History)

Example:

The correct name:

3. Propyl 2. Hexanol

(6C major chains selected are not chosen 7C 7C because if its OH group does not participate).

3. Alcohol Classification
Based on the differences in the location of the bound-OH group on the C atom can be divided into three yatiu Alcohol:

1) Alcohol is if the primary-OH group attached to a primary C atom (atom C 1 C atom that binds the other directly)

Example:

CH3 - CH2 - CH2 - CH2 - OH n. Butanol

2) Secondary alcohols that if the-OH group attached to the secondary carbon atoms (C atoms that bind directly two other C atoms).

Example:

CH3 - CH2 - CH - CH3 2. Butanol

OH

3) tertiary alcohol that is if the-OH group attached to the tertiary C atoms (C atoms that bind directly three C atoms are directly)
