Question

6. a. Write the Lewis structures for CH and CH Determine their AXE formulas. Sketch the molecules and state their geometries. Include the bond angles. (10 points) b. Given that His 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 NH3 react to form H:BNH; so that boron completes its octet. Write all three Lewis structures. (5 points)

Answer 1

1 Cilt Hic ut 4: Lewis structure of Lewis structure of cht CHz Sketch of Celil molecule struct Geometry of Cltz' is pydamidal sketch of Cla molecul Geometry of alte is tedrakech Bond Angle 109.5°

For CH3- AXE formula will be AX3E1

For CH4 AXE formula will be AX4E0
