Concept explainers
(a)
Interpretation:
The Lewis electron dot structure for tricarbon dioxide should be given.
Concept Introduction:
- Lewis structures are diagrams that represent the
chemical bonding of covalently bonded molecules and coordination compounds. - It is also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
- The Lewis structure is based on the concept of the octet rule so that the electrons shared in each atom should have 8 electrons in its outer shell.
Lewis structure for any molecule is drawn by using the following steps,
First the skeletal structure for the given molecule is drawn then the total number of valence electrons for all atoms present in the molecule is determined.
The next step is to subtract the electrons present in the total number of bonds present in the skeletal structure of the molecule with the total valence electrons such that considering each bond contains two electrons with it.
Finally, the electrons which got after subtractions have to be equally distributed such that each atom contains eight electrons in its valence shell.
(b)
Interpretation:
An approximate
Concept Introduction:
Molecular geometry is the shape of a molecule predicted by considering only bond pair of electrons.
Bond angle is the angle between two bonds of a molecule and it is determined based on the electron-domain geometry.
(c)
Interpretation:
An approximate
Concept Introduction:

- Formamide, HC(O)NH2, is prepared at high pressures from carbon monoxide and ammonia, and serves as an industrial solvent (the parentheses around the O indicate that it is bonded only to the carbon atom and that the carbon atom is also bonded to the H and the N atoms). Two resonance forms (one with formal charges) can be written for formamide. Write both resonance structures, and predict the bond angles about the carbon and nitrogen atoms for each resonance form. Are they the same? Describe how the experimental determination of the HNH bond angle could be used to indicate which resonance form is more important.arrow_forwardWhich has the greater bond lengths: NO2 or NO3? Explain.arrow_forwardConsider the following molecules: SiH4, PH3, H2S. In each case, a central atom is surrounded by four electron pairs.

In ho-molytic breakage , each atom in the bond gets one of the shared electrons. In some cases, the electronega-tivity of adjacent atoms affects the bond energy. In heterolytic breakage, one atom gets both electrons and the other gets none;thus, a cation and an anion form.
