Bond-line formula

In these simplified representations called bond line formulas or carbon skeleton dia grams, the only atoms specifically written m are those that are neither carbon nor hydro gen bound to carbon Hydrogens bound to these heteroatoms are shown however... 

Unbranched alkanes are sometimes referred to as straight chain alkanes but as we 11 see m Chapter 3 their chains are not straight but instead tend to adopt the zigzag shape portrayed m the bond line formulas introduced m Section 1 7...

Much of the communication between insects involves chemical messengers called pheromones A species of cockroach secretes a substance from its mandibular glands that alerts other cockroaches to its presence and causes them to congregate One of the principal components of this aggregation pheromone is the alkane shown in the bond line formula that follows Give the molecular formula of this substance and represent it by a condensed formula...

We can use bond line formulas to represent alkenes in much the same way that we use them to represent alkanes Consider the following alkene... 

Bond line formula (Section 1 7) Formula in which connec tions between carbons are shown but individual carbons and hydrogens are not The bond line formula... 

For even more convenience in representing the structures of organic compounds, particularly in printed material, line formulas are used, so-called because they are printed on one line. In line formulas, each carbon atom is written on a line adjacent to the symbols for the other elements to which it is bonded. Line formulas show the general sequence in which the carbon atoms are attached, but in order to interpret them properly, the permitted total bond orders of all the respective atoms must be kept in mind. Again referring to the compounds (a) to (e) described above, the line formulas are as follows ... 

We can use bond-line formulas to represent alkenes in much the... 

SAMPLE SOLUTION (a) Recall when writing bond-line formulas for hydrocarbons that a carbon occurs at each end and at each bend in a carbon chain. The appropriate number of hydrogens are attached so that each carbon has four bonds. Thus the compound shown is... 

Dash formula diagram all atoms, bonds as dashes Bond line formula hide H, show carbon skeleton as... 

The bond-line formula is likely to be the most prevalent on the MCAT. Tn the bond-line formula, line intersections, corners, and endings represent a carbon atom unless some other atom is drawn in. The hydrogen atoms that are attached to the carbons are not usually drawn but are assumed to be present.
