Chemistry Question on Aldehydes, Ketones and Carboxylic Acids
In PO43−the formal charge on each oxygen atom and P − O bond order respectively are
A
(A) − 0.75, 0.0
B
(B) − 0.75, 1.0
C
(C) − 0.75, 1.25
D
(D) − 3, 1.25
Answer
(C) − 0.75, 1.25
Explanation
Solution
Explanation:
PO43ion exist in 4 resonating structures. Bond order of PO43−=Nimber of bonds in the speciesNumber of resonating structives=54=1.253 negative charges of the ion is being shared by 4 oxygen atoms.∴ formal charge on an 0 atom =−34
