Chemistry Question on Chemical bonding and molecular structure
The correct sequence of increasing covalent character is represented by
A
LiCl < NaCl< BeCl2
B
BeCl2 < NaCl< LiCl
C
NaCl < LiCl < BeCl2
D
BeCl2 < LiCl < NaCl
Answer
NaCl < LiCl < BeCl2
Explanation
Solution
We can observe that each of the supplied molecules has a chlorine anion linked to it, but the cations are different. And the cations' order of electronegativity is Na Li Be. Therefore, the covalent character will increase in the following order: NaCl, LiCl, and BeCl2.
So, the correct option is (C): NaCl < LiCl < BeCl2
