Hydroxyl groups are -OH molecules that form the 'alcohols' in organic chemistry.
'Poly' equates to 'many.'
An important polyhydroxyl group is 1, 2-ethanediol (ethylene glycol) C2H4(OH)2
which is in anitfreeze for cars I think.

∙ 12y agosaccharides are polyhydroxy aldehydes or ketones, that is ,they are molecules with more than one hydroxyl group[-OH] and a carbonyl group [c=o] either at the terminal carbon atom [aldose] or the second carbon atom [ketose].

How do you neutralize Boric Acid in water?
By adding polyhydroxy comp. as Glycerol, Mannitol , H3BO3 acts as strong acid and we can titrate it.
Are monomers and polymers of aldehydes and keytones that have hydroxyl groups attached?
No, monomers and polymers of aldehydes and ketones do not have hydroxyl groups attached. Aldehydes and ketones have a carbonyl group (C=O) attached to at least one carbon atom and do not have any hydroxyl groups (-OH) attached to the carbon chain.
What family is formaldehyde in?
Formaldehyde, H2C=O, is the basic member of organic compounds known as aldehydes. Aldehydes are hydrocarbons (chains of carbons with hydrogen attached) with an oxygen atom double-bonded to a carbon.
How will you characterize the rate of reaction of an aldehyde compared to an aliphatic aldehyde?
Typically aromatic groups attached to functional groups increase the reaction over that of an aliphatic groups. Aromatic aldehydes (e.g. benzaldehyde, C6H5.CHO), are also known which undergo a number of chemical reaction which do nor occur for aliphatic aldehydes and which are unique to aromatic aldehydes.
What is the group that distinguishes aldehydes from most other classes of compounds?
hydroxyl
Polyhydroxy derivatives of aldehydes or ketoens are?
Carbohydrates
What is charbohydrants?
any of a class of organic compounds that are polyhydroxy aldehydes or polyhydroxy ketones, or change to such substances on simple chemical transformations, as hydrolysis, oxidation, or reduction, and that form the supporting tissues of plants and are important food for animals and people.
Is an apple a monosaccharide?
Well, basically carbohydrates are the compounds of carbon,hydrogen,oxygen. They are polyhydroxy aldehydes or polyhydroxy ketones. monisaccharide is a carbohydrate. monosaccahrides are sweet and water soluble . monosaccharides include glucose(dextrose), fructose(levulose), galactose,xylose,ribose.
What is polyhydroxy butyrate?
Polyhydroxybutyrate is a polymer with various uses.
Which two groups have the same functional group?
ketones and aldehydes
What kind of alcohols can be used to prepare aldehydes?
All primary (10) alcohols may be oxidized to aldehydes.
Name different types of crbohydrate present in food material?
carbohydrate is an organic compound which has the empirical formula Cm(H2O)n; that is, consists only of carbon, hydrogen and oxygen, with the hydrogen and oxygen in a 1:2:1 atom ratio (as in water). Carbohydrates can be viewed as hydrates of carbon, hence their name. Structurally however, it is more accurate to view them as polyhydroxy aldehydes and ketones.
What is carborhydates?
A carbohydrate is an organic compound with the empirical formula Cm(H2O)n (where m could be different from n); that is, consists only of carbon, hydrogen, and oxygen, with a hydrogen:oxygen atom ratio of 2:1 (as in water). Carbohydrates can be viewed as hydrates of carbon, hence their name. Structurally however, it is more accurate to view them as polyhydroxy aldehydes and ketones. Carbohydrates are an ideal source of energy for the body.
What homologus series is ethanal in?
Aldehydes
What types of aldehydes and ketones would you expect to be water-soluble?
The aldehydes and ketones having three or less carbon atoms are soluble in water.
Aldehydes and ketones may be reduced to?
alcohol
Why are aldehydes more reactive than ketones towards nucleophile?
Aldehydes are less sterically hindered than ketones. Also, aldehydes have fewer electron donating groups (EDG's) which can stabilize an electron-poor area. The extra carbon chain that ketones have that aldehydes do not have are the reason for both of these things. The neighboring carbon to the carbonyl carbon is an EDG and the carbon chain causes steric hindrance.
