Which one of the following statement is correct regarding the formula of a compound?
Answers
Answer:
Hydrogen resembles alkali metals in some properties so it can be placed in the first group of periodic table
Answer:
The halogens react with each other to form interhalogen compounds. The general formula of most interhalogen compounds is AX
n
, where n = 1, 3, 5 or 7, and A is the less electronegative of the two halogens. The compounds which are formed by the union of two different halogens are called inter halogen compounds.
There are never more than two types of halogen in a interhalogen molecule, which are of 4-types.
AX- type : ClF,BrF,BrCl,ICl,IBr
