BF3 - Boron trifluoride


6 Write a chemical equation showing the reaction between ammonia and boron trifluoride BF3 in a Lewis acid-base reaction Show how the covalent bond forms?

The reaction between ammonia and boron trifluoride, BF3If you have recently read the page on covalent bonding, you may remember boron trifluoride as a compound which doesn't have a noble gas structure around the boron atom. The boron only has 3 pairs of electrons in its bonding level, whereas there would be room for 4 pairs. BF3 is described as being electron deficient.The lone pair on the nitrogen of an ammonia molecule can be used to overcome that deficiency, and a compound is formed involving a co-ordinate bond.Using lines to represent the bonds, this could be drawn more simply as:The second diagram shows another way that you might find co-ordinate bonds drawn. The nitrogen end of the bond has become positive because the electron pair has moved away from the nitrogen towards the boron - which has therefore become negative. We shan't use this method again - it's more confusing than just using an arrow.

Are boron and iodine covalent or ionic compound?

Boron and Iodine are elements but in a reaction they would form neither as a covaelent bond and an ionic bond is comepletely separate.Basically, neither can form copounds as covaelent and ionic are bonds not compounds.
