Element 'A' having 5 electrons in its valence shell and principle quantum number value for last electron is 3. The 'ic' acid of element 'A' is tribasic acid and its corresponding salts is known as 'atc' salt. The 'ous acid' 'A' is dibasic acid and its corresponding salts is known as 'its' salts.
[''For example : The salt of sulphuric acid is sulphate salt '' and the salt of sulfurous acid is sulphite salt]
`2xx'ic'` acid of 'A' `-H_(2)O`='x'
How many `sigma` bonds are present in 'x'?

None of these

Verified by Experts

The correct Answer is:

Element A is P
`xrarrH_(4)P_(2)O_(7)`, `{:(" O O"),(" || ||"),(H-O-P-O-P-O-H),(" | |"),(" "O-H" "O-H):}`
