Concept explainers
(a)
Interpretation:
The given phenol has to be named.
Concept Introduction:
When one hydrogen atoms are replaced by a hydroxyl group in benzene is known as phenol. If the other hydrogen atoms present in phenol are replaced by other atoms or groups are known as phenol derivatives.
Phenol derivative with one substituent:
IUPAC system of naming phenol derivative considers phenol to be a part of main name. The numbering is given in a way that the substituent gets the least numbering possible.
Ortho- means disubstitution in 1,2
Meta- means disubstitution in 1,3
Para- means disubstitution in 1,4
In all the above derivatives of phenol, the first position is occupied by hydroxyl group.
Phenol derivatives with two or more substituents:
More than two groups are present in the benzene ring means, their positions are numbered. The numbering is always done in a way that the carbon atom bearing substituent gets the lowest numbering possible. If there is a choice of numbering system, then the group that comes alphabetically first is given the lowest number.

- Name three other products applied in industry obtained from phenol and its uses.arrow_forwardEster compounds often have a sweet, pleasant odor. Many characteristic fruit scents are largely due to the natural presence of one or more ester compounds. As such, artificial scents for foods are often composed of complex mixtures of various esters. The exact identity and ratio of ingredients that compose a particular scent are closely guarded secrets in the food and fragrance industry. Suppose that you are a chemist working for a company that i creating a new line of air fresheners. The company is considering three scents: apple, pear, and pineapple. The project manager has asked you to prepare the ester compounds that are largely responsible for these scents. The structural formulas for these ester compounds are shown here: Alcohols for Air Freshener Project Molar mass Density Cost, per (g/mL) Reagent (g/mol) 1.00 L methanol 32.04 0.79 $46.20 ethanol 46.07 0.79 $112.00 1-propanol 60.10 0.80 $72.70 1-butanol 74.12 0.81 $72.60 Use the structural formulas of the alcohols and…arrow_forwardGive the reagent and the reaction conditions that would distinguish between the following compounds.
