Question

What is homologous serries of alcohol ?

Answer 1

Answer:

Alcohol Homologous Series. 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 CH2 in molecular formulae from neighbouring compounds.

Explanation:

In the field of organic chemistry, a homologous series is a series of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched.This can be the length of a carbon chain,for example in the straight-chained alkanes (paraffins), or it could be the number of monomers in a homopolymer such as amylose.

Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties. (For example, the series of primary straight-chained alcohols has a hydroxyl at the end of the carbon chain.)

Answer 2

Homologous series is the series contain same functional group and number of hydrocarbons changes in case of alcohol functional group is -OH and at the end of name contains 'ol'

Explanation:

• When by changing the number of hydrocarbons suffix in their name remains same is known as homologous series
• In homologous series any suffix is added as per the functional group for example in case of aldehydes 'al' is added and in case of alcohol 'ol' is added
• First five elements of homologous series of alcohol are

1. Methanol   (CH₃OH)
2. Ethanol       ( C₂H₅OH)
3. Propanol     ( C₃H₇OH)
4. Butanol        (C₄H₉OH)
5. Pentanol      (C₅H₁₁OH)
