(a)

Interpretation Introduction

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 Introduction

Interpretation:

An approximate C-to-C-to-O bond angle in tricarbon dioxide has to be given.

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.

Nitrogen trifluoride (NF3) is used in the electronics industry to clean surfaces. NF3 is also a potent greenhouse gas. (A) Draw the Lewis structure of NF3 and determine its molecular geometry. (B) BF3 and NF3 both have three covalently bonded fluorine atoms around a central atom. Do they have the same dipole moment? (C) Could BF3 also behave as a greenhouse gas? Explain why or why not.
Methyl isocyanate, CH3NCO, was made infamous in 1984when an accidental leakage of this compound from a storagetank in Bhopal, India, resulted in the deaths of about3800 people and severe and lasting injury to many thousandsmore. (a) Draw a Lewis structure for methyl isocyanate.(b) Draw a ball-and-stick model of the structure,including estimates of all the bond angles in the compound.(c) Predict all the bond distances in the molecule.(d) Do you predict that the molecule will have a dipolemoment? Explain.
There are two main types of covalent bond breakage. 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. (a) Why is the C−C bond in H₃C−CF₃(423 kJ/mol) strongerthan that in H₃C−CH₃(376 kJ/mol)?(b) Use bond energy and any other data to calculate the heat ofreaction for the heterolytic cleavage of O₂.
