Question Description I’m studying for my Chemistry class and need an explanation. 1. Draw the Lewis structure for BF3, including lone pairs. What is the molecular shape of BF3? tetrahedral bent trigonal planar linear trigonal pyramidal 2. The octet rule states that atoms in molecules share electrons in such a way that each atom has a full valence shell. Determine whether each structure has the correct number of electrons and obeys the octet rule. Classify structures that have the correct number of electrons and obey the octet rule as valid, and those that do not as invalid. 4. Provide the molecular formula and Lewis structure, the expanded structural formula, for the hydrocarbon ball?and?stick model shown. Be sure to include all hydrogen atoms in your Lewis structure. Click on the three?dimensional molecular structure of the compound and drag to rotate it, or use the controls provided. molecular formula: Draw the Lewis structure. 5. Draw a Lewis structure for C2H3Cl. Include all hydrogen atoms and show all unshared electron pairs. None of the atoms bears a formal charge, and all atoms have octets (except for hydrogen atoms, which have duets). Draw C2H3Cl. 6. Draw the Lewis structure for butanal, which has the condensed formula CH3CH2CH2CHO. Show all hydrogen atoms and lone pairs of electrons. Draw butanal. 7. The skeleton of acetic acid is shown. 8. Draw the Lewis structure of COF2. Include lone pairs. 9. Formaldehyde, CH2O
