Aldehydes have diverse properties which make them valuable in an industrial setting. The two most common aldehydes formaldehyde and acetaldehyde can oligomerize and hydrate.
manufacture of resins, dyes, and organic acids.
Formaldehyde can be used to preserve dead animals.
Benzaldehyde is an almond extract
Aldehydes are used in the study of chemistry. Thy are also used in the making of paints, plastics, and synthetic resins.
with fuming nitric acid,formaldehyde is converted in to highly explosive cyclonite which was used in World War-II
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.
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.
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.
hydroxyl
Aldehydes and ketones haven't an -OH group.
ketones and aldehydes
All primary (10) alcohols may be oxidized to aldehydes.
Aldehydes
The aldehydes and ketones having three or less carbon atoms are soluble in water.
alcohol
Carbohydrates
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.
Aldehydes are what create the color in any stain; especially the PAS stain. In reference, the aldehyde are the pigments that can cause permanent staining in a fabric.

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.
