6. a. Write the Lewis structures for CH? and CH4. Determine their AXE formulas. Sketch the molecules in 3D. Determine their geometries and bond angles. (10 points) b. Given that H is less electronegative than C, explain whether the CH? and CH, molecules can have net dipole moments based upon their different geometries. (5 points) c. BH, (borane) and NH; react to form H;BNH, so that boron completes its octet. Write all three Lewis structures. (5 points)
Expert Answer
a.) a.1) Lewis structure of CH3- and CH4 Lewis structure of CH3- Carbon has four valance electrons, and hydrogen has one valance electron. The total number of valance electrons in CH- is 4 + 1(3) + 1(of -ve charge) = 8 electrons. Lewis structure of C
