Bonding writing

So we can disconnect any a,p-imsaturated carbonyl compound along the double bond, writing CH2 at one end and C=0 at tbe other. 

The discormection corresponding to this reaction is again of the C-N bond, writing an amine and a carbonyl group in the right places ... 

Given the information that it has a carbon-carbon bond write a... 

Molecular models such as the one shown often do not explicitly show double and triple bonds Write a Lewis structure for this hydrocarbon showing the location of any multiple bonds Specify the hybndization state of each carbon (You can view this model in more detail on Learn mg By Modeling)... 

Birds excrete nitrogen as uric acid Uric acid is a purine having the molecular formula C5H4N4O3 it has no C—H bonds Write a structural formula for uric acid... 

Dinitrogen pentoxide, N205, when bubbled into water can form nitric acid. Its skeleton structure has no N—N or O—O bonds. Write its Lewis structure. 

Consider the dichromate ion. It has no metal-metal nor oxygen-oxygen bonds. Write a Lewis structure for die dichromate ion. Consider chromium to have six valence electrons. 

STRATEGY Write a Lewis structure for the molecule by using the method outlined in Toolbox 2.1. Decide whether there is another equivalent structure that results from the interchange of a single bond and a double or triple bond. Write the actual structure as a resonance hybrid of these Lewis structures. 

Problem 1.11 Each of the following molecules and ions can be thought to arise by coordinate covalent bonding. Write an equation for the formation of each one and indicate the donor and acceptor molecule or ion. (a) NH (6) be, (c) (CH,),OMgCI, (d) Fe(CO), ... 

The formula CH3N02 fits more isomers than just nitromethane and methyl nitrite. Some, such as carbamic acid, an intermediate in the commercial preparation of urea for use as a fertilizer, are too unstable to isolate. Given the information that the nitrogen and both oxygens of carbamic acid are bonded to carbon and that one of the carbon-oxygen bonds is a double bond, write a Lewis structure for carbamic acid. 

Pentane, a solvent that is found in petroleum, has the formula C5H12. In a C5H12 molecule, each C atom forms four bonds, and each H atom forms one bond. Write three possible structural formulas for pentane. 

Assuming covalent bonds, write electronic structures for the molecules GIF (chlorine fluoride), BrFg (bromine trifluofide), SbCl5 (antimony penta chloHde), HgSg (hydrogen disulfide). In which of these molecules are there atoms with electron configurations that are not noble-gas configurations ... 

A compound C3HgO has a hydroxyl group but no double bonds. Write a structural formula consistent with this information. 

This is the commonest geometry that is encountered in organic molecules, because this is the shape that is adopted by a saturated carbon, i.e. one that is bonded to four other groups by four single bonds. Write down the electronic configuration of the carbon atom in the ground state, i.e. the most stable state. 

Like the hyperconjugation that was discussed above, the lone pair may move into the empty pz orbital to form a n bond. Write the mechanism for this reaction. 

Ozone is a dipolar molecule, and is capable of performing a 1,3-dipolar addition to a carbon/carbon double bond. Write down this step. 

Methyl vinyl ketone, CHjCCH=CH2, can be polymerized by addition polymerization. The addition reaction involves only the C=C bond. Write the structural formula of a four-unit segment of this polymer. 

PROBLEM 1.5 Hydrogen is bonded to fluorine in hydrogen fluoride by a covalent bond. Write a Lewis formula for hydrogen fluoride.
