Functional groups drawing

You learned that functional groups define the families to which organic compounds belong. At this point you should be able to name functional groups when you see them in structural formulas, and, when given the name of a functional group, draw a general example of its stmcture. 

Classify organic molecules according to their functional groups draw the condensed structural formulas for the products of reactions of organic compounds. 

Functional group queries, including a new Functional Group drawing mode. 

Given monomers with two reactive functional groups, draw... 

CHEOPS (we tested Version 3.0.1) is a program for predicting polymer properties. It consists of two programs The analysis program allows the user to draw the repeat unit structure and will then compute a whole list of properties the synthesis program allows the user to specify a class of polymers and desired properties and will then try the various permutations of the functional groups to find ones that fit the requirements. On a Pentium Pro 200 system, the analysis computations were essentially instantaneous and the synthesis computations could take up to a few minutes. There was no automated way to transfer information between the two programs. 

Identify the functional groups in the following model of arecoiine, a veterinary drug used to control worms in animals. Convert the drawing into a line-bond structure and a molecular formula (red = O, blue = N). 

For each of the following compounds, draw an isomer that has the same functional groups. Each intersection of lines represents a carbon atom with the appropriate number of hydrogens attached. 

When solving a problem that asks how to prepare a given product, always work backward. Look at the product, identify the functional group(s) it contains, and ask yourself, "How can I prepare that functional group " In the present instance, the product is a tertiary alkyl chloride, which can be prepared by reaction of an alkene with HC1. The carbon atom bearing the —Cl atom in the product must be one of the doublebond carbons in the reactant. Draw and evaluate all possibilities. 

Strategy To work (a) and (b), start by drawing the parent carbon chain. Put the functional group in the specified position fill out the structural formula with hydrogen atoms. In (c), notice that an —OH group comes from the acid, an H atom from the alcohol. 

Draw structural formulas for compounds containing the functional groups listed in Table 22.2. (Example 22.7 Problems 19-22) 21... 

In the present work a theory for the facile construction of complex molecular orbitals from bond and group orbitals is presented and complemented by accurate drawings of the valence molecular orbitals for over one hundred molecules representing a wide range of connectivities and functional groupings. Direct applications to phenomena in organic chemistry are also discussed. 

Cl l CH2CI 12CH2OCHv (a) Draw a Lewis structure for each molecule, name it, and classify it by functional group, (b) Which molecules are isomers of each other Are any chiral If so, which ones (c) For each molecule, list the types of intermolecular forces that are present, (d) Use your answers to parts (a) and (b) to predict the relative boiling points, from lowest to highest. 

Functional groups can be classified as electron-withdrawing (-/) or electron-donating (-1-/) groups relative to hydrogen. This means, for example, that NO2, a - / group, will draw electrons to itself more than a hydrogen atom would if it occupied the same position in the molecule. 

Bond-line drawings show the carbon skeleton (the connections of all the carbon atoms that build up the backbone, or skeleton, of the molecule) with any functional groups that are attached, such as - OH or -Br. Lines are drawn in a zigzag format, where each comer or endpoint represents a carbon atom. For example, the following compound has 7 carbon atoms ... 

C13-0036. Draw structural formulas and circle and identify the functional groups in the following molecules ... 

C21-0017. Shown below is a ball-and-stick model of the active ingredient in Roundup, a commercial herbicide. Draw the Lewis structure of Roundup and describe its functional groups. 

IR spectrometer with the use of a simple time-resolved technique. 2D IR spectra are especially suited for elucidating various chemical interactions among functional groups. The type of information contained in a dynamic spectrum is determined by the selection of the perturbation (e.g. migration, drawing, aggregation, etc.). 

It is the functional groups that will react. If they are not close together in the original drawing, you should redraw the structures so the functional groups are close together. 

In this section, you learned how to recognize, name, and draw members of the alcohol, alkyl halide, ether, and amine families. You also learned how to recognize some of the physical properties of these compounds. In the next section, you will learn about families of organic compounds with functional groups that contain the C=0 bond. 

Do appreciate that there is no strict convention for how you orientate the structure on paper. In fact, we will turn structures around, as appropriate, to suit our needs. For example, the amino acid tyrosine has three functional groups, i.e. a carboxylic acid, a primary amine, and a phenol. How we draw tyrosine will... 

Problem 14 The oxidation of methyl alcohol produces a substance that has the composition of CH2O. Draw the structure of this molecule and classify it on the basis of its functional group.
