Methane (CH4) and ethane (C2He) are the first two members of the alkane family. Figure 3.2 shows molecular formulas, Lewis structures, and ball-and-stick models for these molecules. The shape of methane is tetrahedral, and all H—C—H bond angles are 109.5°. Each carbon atom in ethane is also tetrahedral, and all bond angles are...

As witir Kjp and K, tire subscript "fc" denotes that this equilibrium constant refers to a particular type of reaction, namely the ionization of a weak base in water. The constant Ky is called the base-dissodation constant The constant always r ers to the equilibrium in which a base reacts with H2O to form the corresponding conjugate acid and OH. Table 16.4 lists tire names, formulas, Lewis structures.

Nitryl fluoride is a reactive gas useful in rocket propellants. Its mass percent composition is 21.55% N, 49.23% O, and 29.23% F. Its density is 2.7 g/L at 20 °C and 1.00 atm pressure. Describe the nitryl fluoride molecule as completely as possible— that is, its formula, Lewis structure, molecular shape, and polarity. 

Structural formulas of this type in which electrons are represented as dots are called Lewis structures... 

Table 1 4 summarizes the procedure we have developed for writing Lewis structures Notice that the process depends on knowing not only the molecular formula but also the order m which the atoms are attached to one another This order of attachment is called the constitution, or connectivity, of the molecule and is determined by experiment Only rarely is it possible to deduce the constitution of a molecule from its molecular formula...

So far we have emphasized structure in terms of electron bookkeeping We now turn our attention to molecular geometry and will see how we can begin to connect the three dimensional shape of a molecule to its Lewis formula Table 1 6 lists some simple com pounds illustrating the geometries that will be seen most often m our study of organic chemistry...

The Lewis rules are relatively straightforward easiest to master and the most familiar You will find that your ability to write Lewis formulas increases rapidly with experience Get as much practice as you can early m the course Success m organic chemistry depends on writing correct Lewis structures... 

Lewis structure (Section 1 3) A chemical formula in which electrons are represented by dots Two dots (or a line) be tween two atoms represent a covalent bond in a Lewis structure Unshared electrons are explicitly shown and sta ble Lewis structures are those in which the octet rule is sat isfied... 

Sometimes, as with PCI5 and SF6, it is clear from the formula that the central atom has an expanded octet Often, however, it is by no means obvious that this is the case. At first glance, formulas such as C1F3 or XeF4 look completely straightforward. However, when you try to draw the Lewis structure it becomes clear that an expanded octet is involved. The number of electrons available after the skeleton is drawn is greater than the number required... 

WEB Glycine, an essential amino acid, has the formula NH2CH2COOH. Its skeleton structure has C—C and C—N bonds but no N—O bonds. Write its Lewis structure. 

Two different molecules have the formula C2H2C12. Draw a Lewis structure for each molecule. (All the H and Cl atoms are bonded to carbon. The two carbon atoms are bonded to each other.)... 

Several compounds have the formula C3H60. Write Lewis structures for two of these compounds where the three carbon atoms are bonded to each other in a chain. The hydrogen and the oxygen atoms are bonded to the carbon atoms.
