Element X is strongly electropositive and Y is strongly electronegative . Both are univalent . The compound formed would be

A

`X^(-)Y^(-)`

B

`X^(-)Y^(-)`

C

`X-Y`

D

`XrarrY`

Text Solution

Verified by Experts

The correct Answer is:
A
`X^(+)Ybar` Beacause electropositive elments form cation and electronegative elements form anion .

Halogens react with each other to form a number of compounds called interalogen compounds. Their genral formula is AX_(n) , where A is less electronegative halogen while X is a more electronegative halogen and n is its number. The interhalogen compounds are essentially convalent and more reactive than the halogens since the bond A-X is weaker than A-A or X-X bond. The reaction of interhalogens are similar to those of halogens. Which halogen shows maximum oxidation state in forming interhalogen compound ?
