What do alkenes and alkynes have in common? (a) At least one point of carbon-carbon bond saturation (b) A carbon-carbon multiple bond (c) A carbon-carbon double bond (d) At most one point of carbon-carbon bonding. What is the molecular formula of an aldehyde which has 40% carbon in...
In organic chemistry, an "enamine" is the rearrangement product of an imine, itself the reaction product of a carbonyl compound — an aldehyde or ketone — with either ammonia or an amine — primary or secondary. Derivation of the term is from the words "alkene" and "amine" — the two ...
-COOH and -COOR, a carbonyl compound, ketone compound or aliphatic, alicyclic or aromatic aldehyde compound containing a methyl group or methylene group in the alpha -position relative to the carbonyl is reacted with an unsaturated compound containing one or more groups from the series listed. ...
If the carbonyl group is at an end of the carbon chain (that is, in an aldehyde group), the monosaccharide is an aldose; if the carbonyl group is at any other position (in a ketone group), the monosaccharide is a ketose.A.正确B.错误的答案是什么.用刷刷题A

p-Anisaldehyde (4-methoxybenzenaldehyde, C8H8O2) is a naturally occurring fragrant phenolic compound that is soluble in acetone. The compound occurs in many plant species including anise, Pimpinella anisum L.; cumin, Cuminum cyminum L.; fennel, Foeniculum vulgare Miller; and garlic, Allium sati...
O-Labeling patterns of ABA-aldehyde, ABA-trans-diol, and ABA indicate that ABA-aldehyde is a precursor to, and ABA-trans-diol a catabolite of, ABA. Exchange of O in the carbonyl of ABA-aldehyde can be the cause of loss of O from the side chain of [O]ABA. Results of feeding ...

Heptanal or heptanaldehyde is an alkyl aldehyde. It is a colourless liquid with a strong fruity odor, which is used as precursor to components in perfumes and lubricants. Emde et al. reported [1] its application on the total syntheses of two acetogenins, squamocin A and squamocin D, ...
