Question

Formal charge of Cl in HClO4?

Answer 1

Explanation:

HClO4 is still neutral because we can look at the formal charges in the Lewis structure to determine the charge of HClO4. The Cl atom would have three double bonds with three oxygen atoms and one single bond with OH, causing the formal charge of Cl to be 0 (7-(0+14/2)).

Answer 2

Answer:

3

Explanation:

• F.C=V-L-1/2*S
• V=VALENCE OF Cl= 7
• L=LONE PAIR (NON BONDED ) = 0
• S=SHARED PAIR (BOND PAIR) = 8
• F.C= 7-0-1/2*8
• F.C= 7-0-4
• F.C OF Cl = 3
