Given below are two statements: 

Assertion (A): Fluorine exhibits only –1 oxidation state whereas other halogens exhibit + 1, + 3, + 5 and + 7 oxidation states.
Reason (R): Other halogens have d orbitals and therefore, can expand their octets and show +1, +3, +5 and +7 oxidation states also.


 

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).

HCl reacts with finely powdered iron, it forms ferrous chloride and not ferric chloride because:
 

1. Formation of Cl2 gas prevents ferric chloride formation
2. Formation of H2 gas prevents ferric chloride formation
3. Formation of [FeCl6]4-  prevent ferric chloride formation
4. Formation of  Fe3H prevents ferric chloride formation
