Question
How many electron pairs are on the boron atom in BCl3?Question 4Select one:a.3b.6c.8d.18e.32
Solution
Boron (B) is in Group 3 of the periodic table and therefore has 3 valence electrons. In BCl3, boron forms 3 covalent bonds with 3 chlorine atoms, using up all its 3 valence electrons. Therefore, boron has 3 electron pairs in BCl3. So, the answer is a. 3.
