Unshared, or lone, electron pairs play an important role in determining the chermical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. The number of unshared pairs at atom a is The number of unshared pairs at atom b is HyC CH The number of unshared pairs at atom e is The number of unshared pairs at atom a is The number of unshared pairs at atom b is HC CH The number of unshared pairs at atom e is

How to draw the line bond formula or lewis structure of a methyl ketone with the chemical formula C6H5C3H5O?

which of the following statement is not true? 1)Nitrogen s relative inertness is due to formation of strong and stable bond between 2 nitrogens atom. 2)the bond energy of N2 is relatively higher that makes it relatively inert. 3)the bond energy of an O-H bond is always the same in all compounds that contain an O-H bond 4)carbon-carbon single bond is the longest among all sorts of carbon-carbon bonds 5)a shorter bond in general ,is a stronger bond than a longer bond
