Concept explainers
(a)
Interpretation:
A resonance structure of the given species is to be drawn.
Concept introduction:
Resonance structures differ in the position of electrons. The position of atoms remains the same. Curved arrows are used to show the movement of a pair of valence electrons. The formal charge on the atoms changes when the lone pair on an atom is converted to a bonding pair or a bonding pair is converted to a lone pair.
(b)
Interpretation:
A resonance structure of the given species is to be drawn.

(c)
Interpretation:
A resonance structure of the given species is to be drawn.
Concept introduction:
Resonance structures differ in the position of electrons only; the position of atoms remains the same. Curved arrows are used to show the movement of a pair of valence electrons. The formal charge on the atoms changes when the lone pair on an atom is converted to a bonding pair or a bonding pair is converted to a lone pair.

- 3) Draw all resonance structures of the following compound. Order the structures by increasing stability.arrow_forwardProblem Draw a Lewis structure and identify the octet-rule exception for (a) H3PO4 (draw two resonance forms and select the more important); (b) BFCl2.Plan We draw each Lewis structure and examine it for exceptions to the octet rule.(a) The central atom is in Period 3, so it can have more than an octet.(b) The central atom is B, which can have fewer than an octet of electrons.arrow_forwardProblem Draw Lewis structures for the following:(a) Ethylene (C2H4), the most important reactant in the manufacture of polymers(b) Nitrogen (N2), the most abundant atmospheric gasPlan We show the structure resulting from steps 1 to 4: placing the atoms, counting the total valence electrons, making single bonds, and distributing the remaining valence electrons in pairs to attain octets. Then we continue with step 5, if needed.arrow_forward
- Draw complete Lewis structures for the following condensed structural formulas.(a) CH3(CH2)3CH(CH3)2 (b) (CH3)2CHCH2Cl(c) CH3CH2COCN (d) CH2CHCHO(e) (CH3)3CCOCHCH2 (f) CH3COCOOHarrow_forwardThe curved arrow notation introduced in Section 1.6B is a powerful method used by organic chemists to show the movement of electrons not only in resonance structures, but also in chemical reactions.Because each curved arrow shows the movement of two electrons, following the curved arrows illustrates what bonds are broken and formed in a reaction. Consider the following three-step process. (a) Add curved arrows in Step [1] to show the movement of electrons. (b) Use the curved arrows drawn in Step [2] to identify the structure of X. X is converted in Step [3] to phenol and HCl.arrow_forwardEach of the following compound is an amine ( ). Which line-angle formulas represent the same compound? Which represent constitutional isomers?arrow_forward
