Atomic orbitals hybridization and

A pair of sp hybrid orbitais forms by interacting an s atomic orbital and one p atomic orbital. The two hybrids point in opposite directions.

All single bonds are sigma bonds. Many kinds of pure atomic orbitals and hybridized orbitals can be involved in sigma bond formation. 

Butadiene The ti molecular orbitals of 1 3 butadiene are shown m Figure 10 10 The four sp hybridized carbons contribute four 2p atomic orbitals and their overlap 

In the manner of Figure 11-18, indicate the structures of the following molecules in terms of the overlap of simple atomic orbitals and hybrid orbitals (a) CH2CI2  

Another type of orbital is one that originates from the mixing of the different atomic orbitals and is called a hybrid orbital. Hybridization (mixing) of atomic orbitals results in a new set of orbitals with different 

Atoms that are linked by electron-pair bonds are positioned so that orbital overlap is maximised. The orbitals used are also sensitive to bond overlap and hybridisation, so that atomic orbitals frequently mix to give hybrid orbitals with greater overlapping power. The shapes of atomic orbitals and hybrid orbitals are quite definite and point in fixed directions. This leads to the fact that covalent bonding is directional. From a geometrical point of view, the array of covalent bonds in a solid resembles a net. 

The introduction of hybrid-based MO s into the theoretical treatment of paraffinic hydrocarbons 50> has made it possible to extend the applicability of Eqs. (3.21) and (3.24) to a wide variety of saturated compounds. The index has been called delocalizability" of an atomic orbital and is defined by the following formulae 60 68>

In a familiar example, a 2s orbital can be mixed with three 2p orbitals to give four hybrid orbitals this can be done in an infinite number of ways, such as (from now on (j> will be used for atomic orbitals and ij/ for molecular orbitals)  

STRATEGY Draw the Lewis structure and determine the electron arrangement about the central atom. The number of orbitals required for the electron arrangement determines the hybridization scheme used, as shown in Table 3.2. Construct the hybrid orbitals from atomic orbitals, using the same number of atomic orbitals as hybrid orbitals. Start with the s-orbital, then add p- and d-orbitals as needed. 

The Lewis structure shows that methyl methaciylate has the formula C5 Hg O2, with 40 valence electrons. You should be able to verily that the two CH3 groups have. s -hybridized carbons, the inner oxygen atom is s hybridized, the outer oxygen atom uses 2 p atomic orbitals, and the three double-bonded carbons are s p hybridized. These assignments lead to the following inventory of a bonds and inner-atom lone pairs
