Explanation:
More is the electronegativity difference between the combining atoms more polar is the compound. Hence, more ionic it will be in nature.
(a) Electronegativity value of P = 2.19
Electronegativity value of Cl = 3.16
Electronegativity value of Br = 2.96
Electronegativity value of F = 3.98
Electronegativity difference of a P-Cl bond = 3.16 - 2.19 = 0.97
Electronegativity difference of a P-Br bond = 2.96 - 2.19 = 0.77
Electronegativity difference of a P-F bond = 3.98 - 2.19 = 1.79
Since, a P-F bond has the highest electronegativity difference. Therefore, is the most ionic compound and
is the least ionic compound.
(b) Electronegativity value of B = 2.04
Electronegativity value of N = 3.04
Electronegativity value of C = 2.55
Electronegativity value of F = 3.98
Electronegativity difference of a B-F bond = 3.98 - 2.04 = 1.94
Electronegativity difference of a N-F bond = 3.04 - 3.98 = 0.94
Electronegativity difference of a C-F bond = 3.98 - 2.55 = 1.43
Since, a B-F bond has the highest electronegativity difference. Therefore, is the most ionic compound and
is the least ionic compound.
(c) Electronegativity value of Se = 2.55
Electronegativity value of Te = 2.1
Electronegativity value of Br = 2.96
Electronegativity value of F = 3.98
Electronegativity difference of a Se-F bond = 3.98 - 2.55 = 1.43
Electronegativity difference of a Te-F bond = 3.98 - 2.1 = 1.88
Electronegativity difference of a Br-F bond = 3.98 - 2.19 = 1.02
Since, a Te-F bond has the highest electronegativity difference. Therefore, is the most ionic compound and
is the least ionic compound.
Answer : The correct option is, (D) CO₂, BCl₃, and Fe³⁺
Explanation :
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
(a)
It is a Lewis-acid because it can accepts electron pairs.
(b)
It is not a Lewis-acid because it can not accepts electron pairs but it is a base because it can donates and accept hydrogen ion.
(c)
It is a Lewis-acid because it can accepts electron pairs because it has an incomplete octet and an empty 2p orbital.
(d)
It is a Lewis-acid because it can accepts electron pairs.
Hence, the ions which behave as Lewis acids are, CO₂, BCl₃, and Fe³⁺
