Why is the 2-furaldehyde semicarbizone kinetically favored over the cyclohexanone semicarbazone?
With enough activation energy, the most energetically stable product will be formed. In this case, 2-furaldehyde semicarbazone is more stable than cyclohexanone semicarbazone because 2-furaldehyde semicarbazone has an aromatic ring.
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

What is the melting point for benzalacetone semicarbazone?

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.
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
Polyhydroxy derivatives of aldehydes or ketoens are?
Carbohydrates
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.
What is aldehydes in PAS stain?
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.
