Chapter 3, Problem 14EQ
Interpretation Introduction
Interpretation:
The leaving group in the given molecule is to be determined in order identify the positively charged and neutral fragments produced during mechanism.
Concept Introduction:
Heterolytic cleavage of sigma bond occurs under a variety of conditions. The mechanism of bond cleavage is as shown below,
The arrow in the above mechanism indicates that the sigma electrons form A-B bond are leaving A and becoming the exclusive property of B. Since the fragment A is formally losing one electron, it must become positively charged and B must become negatively charged since it gains an electron.

- Why is this theory successful? Can you name some of the limitations of the theory? Drag the appropriate items to their respective bins. to determine the shape of the molecule or ion to determine the formulas of ionic compounds Lewis theory allows us to account for the paramagnetism of some species (e.g. oxygen) to determine how the bonds in the molecules and ions form to predict what molecules or ions will be stable, which will be more reactive, and which will not exist to account for the low melting points and boiling points of molecular compounds compared to ionic compounds Lewis theory does not allow us Reset Helparrow_forwardHydrocarbons are not the only things subject to combustion. Elemental sulfur will burn brightly to form a combination of sulfur dioxide and sulfur trioxide. The electronegativities of oxygen and sulfur are 3.5 and 2.5, respectively.
