Hi Uday,

This is a starightoward requirement to implement in JIRA.

You have the add a validation on the transition which is taking the ticket to "re-open status". Basically in the workflow configuration you can add "comments screen" on the trasition such that a comment box appears when transition is to the re-opn status and also add a validation that the comments box should be filled otherwise the transition will fail.

I will suggest to you to use the comments box rather an custom field called "reason"

You can also use the plugin script runner for the same purpose.
