Organic compounds oxygen hybridization

ZnO-based organic (eosin) inorganic hybrid semiconductor compounds have been grown heteroepitaxially in one step at low temperature by a simple electrochemical method from an oxygenated zinc chloride aqueous solution [163]. 

An organic compound distilled from wood was found to have a molar mass of 32.04 g-mol 1 and the following composition by mass 37.5% C, 12.6% H, and 49.9% O. (a) Write the Lewis structure of the compound and determine the bond angles about the carbon and oxygen atoms, (b) Give the hybridization of the carbon and oxygen atoms, (c) Predict whether the molecule is polar or not. 

With simple organic compounds covalent bonds result from the combination of the four unpaired electrons in the sp -hybridized orbitals of carbon with the impaired electrons of hydrogen or oxygen. 

It is probably fair to say that life reflects and depends on three chemical aspects (1) hybridization of carbon and oxygen (as well as nitrogen), (2) the facile way carbon atoms may bind to other carbon atoms, and (3) the unique ability of hydrogen to form H-bonds. The catenation and tetrahedral geometry of the carbon atoms are the fundamental features of all organic compounds in cells. However, the most abundant molecule in any living cell is water. 

How does the hybridization of the starred carbon atom change, if at all, in going from reactants to products c. What is the systematic name of the product Hint In this shorthand notation, aU tbe C—H bonds have been elimi-nated and the lines represent C—C bonds, unless shown differently. As is typical of most organic compounds, each carbon atom has four bonds to it and the oxygen atoms have only two bonds.)... 

The second area that has exploded during the last decade concerns materials that involve open-frameworks that are constructed from both inorganic and organic components we shall refer to them collectively as hybrid materials and wUl cover them in two separate sections. The first will examine the so-called coordination polymers [14] in which molecular coordination compounds are connected by organic linkers to form chains, sheets or 3-D networks. The second class involves extended metal-oxygen-metal networks that are decorated by organic ligands we shall refer to these as hybrid metal oxides. 

Carbonyl compounds also have two nonbonding lone pairs on the oxygen atom. In organic chemistry texts, these are sometimes shown as two equivalent sp2-hybridized lobes (rabbit s ears). While hybridization has no effect on the total energy, the two degenerate nsp2 orbitals are inappropriate as a basis set to discuss one-electron properties such as ionization potentials or n,jt transitions. Rather, the symmetry-adapted lone pairs...
