1. boron-fluorine single bonds are approximately 1.52A(152pm) in length. in BF3, the bond lengths are 1.30A. propose an explanation for this discrepancy, making use of resonance structures to illustrate your answer.

2. BF3 is often sold as a complex with dimethyl sulfide, CH3SCH3. Draw Lewis dot structure for dimethy sulfide, and for the BF3 CH3SCH3 complex, showing formal charges where appropriate Identify the Lewis acid and Lewis Base in the interaction

3. Would you expect theboron-fluorine in theBF3 CH3SCH3 complex to be longer or shorter than those in "free"(uncomplexed)BF3? explain your answer
