Exploding grenade produces disorder (7)
I believe the answer is:
derange
'disorder' is the definition.
(I know that derange is a more specific form of the action disorder)
'exploding grenade' is the wordplay.
'exploding' indicates anagramming the letters.
'grenade' is an anagram of 'DERANGE'.
'produces' acts as a link.
(Other definitions for derange that I've seen before include "cause confusion" , "Remove from order" , "Craze" , "Make mad" , "Put into confusion" .)
