We’re being asked to draw the Lewis structure of the ammonia-boron trifluoride reaction product.
We know that Ammonia, NH3 reacts with boron trifluoride, BF3 to form a stable compound.
**Recall rules for naming covalent compounds:
This type of reaction occurs between a Lewis acid and a Lewis base to form a Lewis acid-base adduct or complex.
Let’s first define a Lewis acid and a Lewis base.
Based on the Lewis definition:
Lewis acid is an electron pair acceptor.
Some characteristics of a Lewis acid:
• When hydrogen is connected to an electronegative element such as P, O, N, S or halogens
▪ hydrogen gains a partially positive charge → makes hydrogen act as a Lewis acid
• Positively charged metal ions
Ammonia reacts with boron trifluoride to form a stable compound.
Draw the Lewis structure of the ammonia-boron trifluoride reaction product.
