Alcohols - Creative Chemistry
A general formula is a chemical formula used to represent the members of a homologous series. The general formula for the alcohols is C n H 2n+1 OH. Hexanol molecules, for example, contain six carbon atoms: n = 6 2n + 1 = (2 × 6) + 1 = 13. So the molecular formula for …

Methanol (CH 3 OH) and ethanol (CH 3 CH 2 OH) are the first two members of the homologous series of alcohols. Alcohols with one to four carbon atoms are frequently called by common names, in which the name of the alkyl group is followed by the word alcohol:
Alcohol Homologous Series: Easy exam revision notes for GSCE …
The alcohols which only contain one hydroxyl group attached to a saturated carbon form a homologous series. A hydrocarbon homologous series is a series of hydrocarbons which: Have the same general formula; Differ by CH 2 in molecular formulae from neighbouring compounds; Show a gradual variation in physical properties i.e. boiling and melting ...
Homologous Series of Alkanes, Alkenes and Alkynes with …
Alkanes with general formula C n H 2n+2, alkenes with general formula C n H 2n and alkynes with general formula C n H 2n-2 form the most basic homologous series in organic chemistry. The successive members vary from each other by a CH 2 unit.

2024年9月4日 · What is Homologous Series? The homologous series is the group of organic compounds that differ from each other by a methylene (–CH2) group. The simplest example of homologous series is the first four hydrocarbons; methane, ethane, propane, and butane with chemical formulas of CH4,CH3CH3, CH3CH2CH3, and CH3CH2CH2CH3 respectively.
