Question

Based on the Lewis structure of BCl3, the number of electron pairs in the valence shell of boron atom in the BCl3 molecule is

Answer 1

As per the Lewis structure of BCl, it has three valence electrons.

• The BCl3 molecules do not contain lone pairs and are a planar structure.

• The BCL3 has the shape of a trigonal planar.

• Boron will be the central atom in the BCl3 molecule which contains three bonded atoms but no lone pair of electrons. It's also said its steric number is 3.

Answer 2

Answer:

Six electrons

Explanation:

According to Lewis structure of BCl3, the number of electron pairs in the valence shell of boron atom in the BCl3 molecule is three means total of 6 electrons in outermost shell

BCl3 is a trigonal planar molecule and its central atom is bonded with 3 chlorine molecules in a trigonal structure

Lewis structure is also called as dot structure, as it represents the electrons in bonding as dots
