Amide Lewis Structural Formulas

Lewis formulas are the major means by which structural information is communicated in organic chemistry. These structural formulas show the atoms, bonds, location of unshared pairs, and formal charges. [Pg.51]

Two or more Lewis formulas, differing only in the placement of electrons, can often be written for a single compound. In such cases the separate structures represented by the Lewis formulas are said to be in resonance, and the true electron distribution is a hybrid of the electron distributions of the contributing structures. [Pg.51]

The amide function is an important structural unit in peptides and proteins. Formamide, represented by the Lewis structure shown, is the simplest amide. It is a planar molecule with a dipole moment of 3.7 D. Lewis structures I-IV represent species that bear some relationship to the Lewis structure for formamide. [Pg.51]

68 Formamide is a planar molecule. According to VSEPR, does the structural formula given for formamide satisfy this requirement [Pg.51]

69 Which Lewis formula is both planar according to VSEPR and a resonance contributor of formamide [Pg.51]

Given a Lewis structure, a condensed formula, or a line drawing for an organic compound, identify it as representing an alkane, alkene, alkyne, arene (aromatic), alcohol, carboxylic acid, ether, aldehyde, ketone, ester, amine, or amide. [Pg.697]

Both nitramide and hyponitrous acid have the formula H2N2O2. Hyponitrous acid is a weak diprotic acid nitramide contains the amide group (—NHg). Draw plausible Lewis structures for these two substances. [Pg.1085]
