Interpretation:
It is to be explained how the molecules with the general formula
Concept introduction:
The dipole moment of a molecule is a measure of the magnitude of its dipole. A dipole moment is a vector, which has both magnitude and direction. Bond polarity originates from bonds between atoms of different electronegativity. The symmetry of molecules also predicts the polarity of the molecule.
The net dipole moment is shown by adding the vectors of the individual bond dipoles together. The tetrahedral molecules containing polar bonds may or may not be polar depending on their structure. In square planar geometry for the general formula

- Methyl isocyanate, CH3 -N= C = O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As a historical note, an industrial accident in Bhopal, India, in 1984 resulted in leakage of an unknown quantity of this chemical into the air. An estimated 200,000 people were exposed to its vapors, and over 2000 of these people died. Q.) Write a Lewis structure for methyl isocyanate and predict its bond angles. What is the hybridization of its carbonyl carbon? Of its nitrogen atom?arrow_forwardFor a given molecular formula of a hydrocarbon, such as C6H14, draw the structural formulae of its different structural isomers. For a given structural isomer, be able to draw several diagrams that all represent the same isomer that has been transformed by (a) rotation of the whole molecule and/or (b) rotation around single covalent bondsarrow_forwardFor a molecular formula of CsH6O: e a) Draw Lewis structures, showing all bonding and non-bonding electrons, for one compound with an alcohol functional group; one with an ether functional group; one with a ketone functional group; and one with an aldehyde functional group. For each compound, indicate all bond angles and build a molecular model. Indicate whether each pair of valence electrons is non-bonding (n) or o- or л-bonded. For each atom, indicate the corresponding orbitals that are involved (e.g. nsp3, osp3-sp3, etc.). b) c)arrow_forward
- C. Alkenes 1. Construct a model of ethene (C₂H4) by joining two carbon atoms with a double bond. Toggle between skeletal and full Lewis structures by clicking the C-H tool. Note the trigonal planar geometry of the bonds around each carbon atom, and that the carbon-carbon double bond has restricted rotation. Observe that the six atoms in ethene all lie in the same plane, and the double bond is a fixed geometry within the molecule. 2. Add a CH3- group to each of the doubly-bonded carbons to create a four-carbon alkene with the double bond between carbons 2 and 3. Note that the CH3- groups can be attached in two different ways: Both CH3- groups on the same side of the fixed geometry of the double bond. The two CH3- groups on opposite sides of the double bond. Click the broom to tidy up the structures; convert each to a ball-and-stick model clicking the 2D to 3D tool. Take scr prints of your MolView structures, showing both the Lewis structure and 3D model. ● Below, draw structures for…arrow_forwardIn C3H4 Which orbitals overlap to form the sigma bond between an outer carbon and the central carbon atom in this molecule?arrow_forwardSketch the hydrogen bond(s) that form between two molecules of ethanol and one nitrogen trihydride molecule and one dihydrogen monoxide molecule. Show the proper VSEPR shapes of all molecules (meaning VSEPR shapes with proper bond angles) and used dotted or dashed lines to indicate the hydrogen bonds. Indicate 4 different H-bonds: 1) ethanol and nitrogen trihydride 2) ethanol and dihydrogen monoxide 3) dihydrogen monoxide and nitrogen trihydride and then 4) between the two ethanol molecules.arrow_forward
- A. Structural Isomerism of Alkanes Construct models for the five alkanes that have the molecular formula C6H14. All five of your models should have the same number of each type of atom, but they should have the atoms connected in a different order. Thus the molecules they represent are structural isomers of one another. Note the tetrahedral geometry of each carbon atom. Draw an extended and a condensed structure (NOT skeletal/line angle) of each structural isomer, then determine its IUPAC name. Recall that since the IUPAC name specifies the number of each type of atom and how they are connected, each structural isomer will have a different name. Each name should very specifically describe the structure.
