A phenol is a benzene ring with an hydroxl (OH) group attached. A polyphenol is composed of many such phenols strung together.
In terms of everyday life, this description doesn't mean much. A number of fruits and vegetables are being studied based on their polyphenol content, as it's thought that these polyphenols may be responsible for the beneficial effects of these products. Pomegranates and grapes (especially in red wine) are known to be high in polyphenols. Eat your fruits and vegetables.

JudyPolyphenols are compounds that contain multiple phenol groups in their structure, while phenols are a class of organic compounds characterized by a hydroxyl group (-OH) attached to a benzene ring. Polyphenols have multiple phenol groups and exhibit antioxidant properties, whereas phenols may or may not have multiple phenol groups and can have a range of functions beyond just antioxidant activity.

Why do phenols alter pH?
Phenols have a low acidity.
What is observed when phenols are used in Baeyers test?
Phenols give a positive test.
What compound is known for its inability to dissolve in water?
phenols
Do phenols oxidize?
Yes, phenols can undergo oxidation reactions when exposed to oxygen or other oxidizing agents. This process can lead to the formation of quinones and other oxidized products.
Why does a banana brown faster in the refrigerator than on the counter at room temperature?
Bananas ripen faster in the fridge due to the cold temperatures slowing down the enzymatic reactions that cause ripening. Additionally, the moisture in the fridge can also accelerate the browning process.
