A-4.Write a correct Lewis structure for each of the following. Be sure to show explicitly anyunshared pairs of electrons.(a)Methylamine, CH3NH2(b)Acetaldehyde, C2H4O (the atomic order is CCO; all the hydrogens are connected tocarbon.)A-5.What is the molecular formula of each of the structures shown? Clearly draw any unsharedelectron pairs that are present.A-6.Which compound in Problem A-5 has(a)Only sp3-hybridized carbons(b)Only sp2-hybridized carbons(c)A single sp2-hybridized carbon atomA-7.Account for the fact that all three sulfur–oxygen bonds in SO3are the same by drawing theappropriate Lewis structure(s).A-8.The cyanate ion contains 16 valence electrons, and its three atoms are arranged in the orderOCN. Write the most stable Lewis structure for this species, and assign a formal charge toeach atom. What is the net charge of the ion?A-9.Using the VSEPR method,(a)Describe the geometry at each carbon atom and the oxygen atom in the followingmolecule: CH3OCH?CHCH3.(b)
