Concept explainers
(a)
To determine: The line-angle structure for the given condensed structural formula
Interpretation: The line-angle structure for the given condensed structural formula
Concept introduction: The structure in which carbon atoms are indicated by corners and ends of the lines are called “line-angle” structures. In such structures each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds. The lone pair of electrons is shown by a pair of dots.
Condensed formulas are those formulas which are written without showing all the individual bonds. “In condensed formulas double or triple bonds are often drawn as they would be in a Lewis structures.”
