(a)
Interpretation:
Interpret whether the bond in SeF2 is polar or non-polar.
Concept Introduction:
Partial charge is the charge appears on the element in a molecule having difference in their electronegativity. The element with higher electronegativity appears to carries partial negative charge while the element with lower electronegativity or electron releasing nature results in carrying partial positive charge on it.
The nuclear charge increases from left to right in periodic table due to which the electronegativity also increases.
The atomic size increases from top to bottom in periodic table due to the addition of an extra shell. This results in decreasing the electronegativity.
(b)
Interpretation:
Interpret whether the bond in PBr3 is polar or non-polar.
Concept Introduction:
Partial charge is the charge appears on the element in a molecule having difference in their electronegativity. The element with higher electronegativity appears to carries partial negative charge while the element with lower electronegativity or electron releasing nature results in carrying partial positive charge on it.
The nuclear charge increases from left to right in periodic table due to which the electronegativity also increases.
The atomic size increases from top to bottom in periodic table due to the addition of an extra shell. This results in decreasing the electronegativity.
(c)
Interpretation:
Interpret whether the bond in SiF4is polar or non-polar.
Concept Introduction:
Partial charge is the charge appears on the element in a molecule having difference in their electronegativity. The element with higher electronegativity appears to carries partial negative charge while the element with lower electronegativity or electron releasing nature results in carrying partial positive charge on it.
