Hi! I would like to know if what I'm thinking is correct. Please help me as to I'm confused 1. If atom "X" has a high Electronegativity, then that means that it can take Electrons from atom "Y" with a low Electronegativity easily causing atom "X" to have a more negative charge "-" and atom "Y" a more positive charge "+". Is this statement correct? 2. Considering statement number 1, does this mean that an atom with a high Electronegativity would most likely have a negative charge "-"? 3. How about a compound? For example is a Grignard reagent compound "RMgX" where "R" refers to any Hydrocarbon, "Mg" refers to Magnesium, and "X" as a halide. I would like to know how Electronegativity works with a Grignard reaction in forming a new carbon-carbon compound. When carbon dioxide "CO2" is added to the Grignard reagent. Here is what happens as shown in 3.1. 3.1. RMgX + CO2 -> RCOOMgX Then you hydralize it to form the new carbon-carbon compound in 3.2. 3.2. RCOOMgX + H2O -> RCOOH + Mg(OH)X Regarding that reaction, with the bonding of carbon in "R" and carbon "C", how was their Electronegativity affected (about the increase or decrease in Electronegativity or Charge so carbon "R" can form a bond with carbon "C") so they can form a bond as well as it's relationship with magnesium's "Mg" Electronegativity? I don't quite get the explanation in the link http://wiki.answers.com/Q/Why_Magnesium_is_necessary_for_Grignard's_reagent#slide1 If you could provide a simple and easy to understand explanation in layman's term if possible. I have an admission exam that will include this topic. Thank you.
