MCQ

Molecule which contains only bonded pairs of electrons on the central atom is:

A
H₂O
B
NH₃
C
BeCl₂
D
BF₃

✓

Answer

BeCl₂

Explanation:

Be has 2 electrons in the valence shell (it belongs to group 2 of the periodic table).

Now both the electrons are involved in bond formation with both the Cl atoms. It comprises only bonded pair of electrons.

So, there are no lone pairs in the Be atom.
