true
Ammonium Boron Trifluoride.
Boron Trifluoride has only 6 electrons in it's outer shell, and is more stable with 8. Therefore, it will react with molecules that have a free electron pair. Methane does not have a free pair, so it doesn't react.

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.
