Concept explainers
(a)
Interpretation:
Whether two unique configurations about double bond are possible in the given compound is to be explained.
Concept introduction:
For a given double bond, cis and trans configurations are possible if the exchange of two groups on one of the doubly bonded atoms results in a different molecule. If one of the carbon atoms of the double bond has two identical atoms or groups attached, then that double bond will not have two distinct configurations. Two groups are cis to each other if they are on the same side of a double bond, and they are trans to each other if they are on opposite sides.
(b)
Interpretation:
Whether two unique configurations about the double bond are possible in the given compound is to be explained.

- Linoleic acid is an essential fatty acid found in many vegetable oils, such as soy, peanut, and cottonseed. A key structural feature of the molecule is the cis orientation around its two double bonds, where R1 and R2 represent two different groups that form the rest of the molecule.

You muse about all the molecules that chemists draw on a two-dimensional board and wonder which ones are actually planar, existing basically as they appear on the board, and which ones are not plane but rather three-dimensional. Answer the following questions. What is the geometry and hybridization of the carbon in CH4? What is the geometry and hybridization of each central carbon atom in the remaining molecules? Draw each molecule showing the bonds and identify each bond in all the molecules as s or p. What are the specific orbital overlaps (i.e., sp3-sp3) that are in each of the molecules? What are the bond angles for each central atom in each molecule?

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.
