Aldehyde drawing structure

ThomsonNOW Click Organic Interactive to use a web-based palette to draw structures of aldehydes and ketones based on their IUPAC names. 

There is a compound called propanol with structural formula CH3CH2CH2OH. If it is oxidized carefully, an aldehyde called propionaldehyde is obtained. Vigorous oxidation gives an acid called propionic acid. Draw structural formulas like those shown in Figures 18-6 and 18-7 for propionaldehyde and propionic acid.

Q Identify alcohols, ethers, aldehydes, ketones, carboxylic acids, and esters, and draw structural formulas for examples. 

When we write aldehydes as R-CHO, we have no choice but to write in the C and H (because they re part of the functional group —one Important instance where you should ignore Guideline 3 for drawing structures. Another point always write R-CHO and never R-COH, which looks too much like an alcohol. 

Draw structural formulas for an aldehyde and a ketone that contain the fewest number of carbon atoms possible. 

Draw structural formulas and give lUPAC names for all the isomeric aldehydes and ketones that have the molecular formula... 

Draw structural formulas for propanal and propanone. From these formulas, do you think that aldehydes and ketones are isomeric with each other Show evidence and substantiate your answer by testing with a four-carbon aldehyde and ketone. 

Draw structural formulas for the four aldehydes with molecular formula CgHioO. Which of these aldehydes are chiral (See Example 12.2)... 

Compound A has molecular formula C7Hi2-Hydrogenation of compound A produces 2-methylhexane. Hydroboration-oxidation of compound A produces an aldehyde. Draw the stmcture of compound A, and draw the structure of the aldehyde produced upon hydroboration-oxidation of compound A. 

C13-0003. Draw one complete specific line structure for each of the following (a) an amine with the formula Cg Hi 5 N (b) an ester with at least seven carbon atoms (c) an alcohol with a molar mass of 74 g/mol and (d) a molecule with at least ten carbons that contains an aldehyde group and a phenyl ring... 

Draw a condensed structural diagram for each aldehyde or ketone. 

Draw and recognise structures of simple organic compounds l, an aldehyde, acetone, n-butanol..,). Any organic text will tell you about this. 

Figure 16-31 (A) Structure of molybdopterin cytosine dinucleotide complexed with an atom of molybdenum. (B) Stereoscopic ribbon drawing of the structure of one subunit of the xanthine oxidase-related aldehyde oxidoreductase from Desulfo-vibrio gigas. Each 907-residue subunit of the homodimeric protein contains two Fe2S2 clusters visible at the top and the molybdenum-molybdopterin coenzyme buried in the center. (C) Alpha-carbon plot of portions of the protein surrounding the molybdenum-molybdopterin cytosine dinucleotide and (at the top) the two plant-ferredoxin-like Fe2S2 clusters. Each of these is held by a separate structural domain of the protein. Two additional domains bind the molybdopterin coenzyme and there is also an intermediate connecting domain. In xanthine oxidase the latter presumably has the FAD binding site which is lacking in the D. gigas enzyme. From Romao et al.633 Courtesy of R. Huber.

The molecular formula, C4H10O, tells us that compound A is saturated. The fact that A can be oxidized with PCC to an aldehyde (note that B gives a positive Tollens test) tells us that A is a primary alcohol. We can draw only two structures for A that are consistent with these data ... 

We have covered several oxidants that use a multi-valent atom (Cr, Cl, S, or I) as their active species, going from a higher oxidation state before the oxidation to a lower oxidation state after oxidizing the alcohol. Draw the structure of the following atoms, before and after the oxidation of an alcohol to a ketone or aldehyde. How many bonds to oxygen does each atom have before and after the oxidation ... 

Draw and name ketones and aldehydes, and use spectral information to determine their structures. 

Q Name ketones and aldehydes, and draw the structures from their names. Identify their hydrates, acetals, imines, and other derivatives. Problems 18-37, 38, 40,41, and 61... 

Draw the structure of the acyclic polyhydroxy aldehyde that cyclizes to each hemiacetal. 

Problem 21.15 Draw resonance structures to account for the unusual stability of an a,j8-unsaturated aldehyde or ketone. What is the significance of these structuies in terms of orbitals (See Sec. 8.17.)... 

The conjugate addition of a nucleophile to an a, -unsaturated ketone-or aldehyde is due to the same electronic factors that are responsible for direct addition. We ve seen that carbonyl groups are polarized so that the carbonyl carbon is positive, and we can even draw a dipolar resonance structure to underscore the point ...
