The structure of phenol. ... Phenol form characteristic coloured iron complexes when treated with neutral ferric chloride solution. Chapter 3 Alcohols, Phenols, and Ethers 2 3 Alcohols 4 The Hydroxy (—OH) Functional Group •The hydroxyl group (—OH) is found in the alcohol and phenol functional groups.

The simplest way to draw the structure of phenol is: Phenol itself is the only one of the family that you are likely to need to know about for UK A level purposes. The position and name of the functional group are added as a prefix of the name phenol or benzenol. cloves and other plants. Alkanol: An alcohol where the hydroxyl group is bound to an alkyl group, with the general formula C n H 2n+1 OH. ). Alcohol: An organic compound in which the hydroxyl functional group (–OH) is bound to a saturated carbon atom. Phenol is the simplest member of a family of compounds in which an -OH group is attached directly to a benzene ring. We have already seen the simplest possible example of an alcohol functional group in methanol. Not to be confused with phenol, fennel, or funnel, or pH. –in phenols, —OH is connected to a benzene ring. The eponymous member of this grouping is the carboxylic acid functional group, in which the carbonyl is bonded to a hydroxyl (OH) group. Tests for the Functional Groups Present in Organic Compounds. Eugenol (or “4-allyl-2-methoxyphenol or 2-Methoxy-4-(2-propenyl)phenol) is a natural oil extracted from e.g. The properties of a compound are largely determined by the functional group. Aim: Systematically identify the functional groups in the given organic compound and perform the confirmatory tests after identifying the functional groups. Alcohols and Phenols. The key difference between alcohols and phenols is that the alcohols are organic compounds containing –OH group as an essential component whereas the phenols are a group of alcohols which contains –OH group and a benzene ring as essential components..


(Phenyl is pronounced with the accent on phen-, whereas phenol is pronounced with the accent on -ol.) In IUPAC system phenol would be named as benzenol. The question is to mention ‘some’ characteristics of the functional groups which is a rather vague question. The carbon contains hydroxy group (-OH) numbered as 1 and then continue numbering in such a way that the other functional group gets least number as possible.
There are aliphatic and aromatic compounds in organic chemistry, which share the same functional groups. (Note: that’s not the same as hydroxide, OH-, which is ionic.) Add a drop of pyridine and stir. Procedure (for water-insoluble phenols or less reactive phenols) A more sensitive test for phenols consists of dissolving or suspending 15 mg of the unknown in 0.5 mL of methylene chloride and adding 3-5 drops of a 1% solution ferric chloride in methylene chloride. Molecules of organic compounds except that of hydrocarbons can be divided into two parts, a reactive part which is referred to as functional group and a skeleton of carbon atoms called alkyl group. As the name implies, carboxylic acids are acidic, meaning that they are readily deprotonated to form the conjugate base form, called a carboxylate (much more about carboxylic acids in the acid-base chapter! –in alcohols, a hydroxyl group is connected to a carbon atom. Phenol: An alcohol where the hydroxyl group is bound to a phenyl group, with the formula C6H5OH. In the alcohol functional group, a carbon is single-bonded to an OH group (this OH group, by itself, is referred to as a hydroxyl).If the central carbon in an alcohol is bonded to only one other carbon, we call the group a primary alcohol.

Phenyl (phenyl group; Ph): A portion of molecular structure equivalent to benzene minus one hydrogen atom: -C 6 H 5.Sometimes abbreviated as Ph. Standard Phenol. Illustrated Glossary of Organic Chemistry. Phenol.
