Concept explainers
The skeleton is benzaldoxime is
The number of valence electrons is as follows: from the phenyl group. ___; from each of two hydrogens, ___; from the carbon atom, ___; from the nitrogen atom, ___; and from the oxygen atom, ___, for a total of ___. Filling in the skeleton with single bonds and adding the appropriate unshared pairs gives
_____________________
The number of electrons in the functional group of this trial structure is ___, which is ___ too many. Removing an unshared pair from carbon and nitrogen and adding a second bond between them gives
_____________________
in which carbon, nitrogen, and oxygen have their customary valences of ___, ___, and respectively. The alternative structure with a double bond between nitrogen and oxygen is
_____________________
This structure is not acceptable because it requires carbon and oxygen to exhibit the unfamiliar valences of ___ and ___.

Draw a diagram of a long-chain molecule of polyethylene that consists of six units (or mers) of ethylene along with the starting and endpoint OH-. Include bonds in your diagram.arrow_forwardgive the nomenclature or the structure of the following molecules of item #21 to #25.arrow_forward
- The skeleton of benzyldimethylamine is The number of available valence electrons is as follows: from the benzyl group, ___; from each of two methyl groups, ___; and, from the nitrogen atom, ___, for a total of ___. Filling in the skeleton with single bonds gives ____________________________ and adding the appropriate unshared pair gives ____________________________ The number of electrons in the functional group of this structure is ___, and the structure is (correct, incorrect).arrow_forwardTo satisfy the octet rule, fullerenes must have doublebonds.
