This question is far too specific to be answered on a general website. Moreover, you should consult an attorney to determine which type of bankruptcy -- chapter 7, chapter 11, chapter 13, etc. -- is right for your particular situation. Each chapter has its own requirements, so it's best to let an attorney review your situation for your best option. But yes, Chapter 11 does still exist although it is not as common as Chapter 7 or 13.

Yes, chapter 11 bankruptcy still exists. However, it would be rare, but not unheard of, for an individual to use chapter 11 bankruptcy. Meet with a qualified bankruptcy attorney, one experienced in handling tax matters to figure out if bankruptcy is a good option, and if so, which chapter is best.
Chapter 11 still exists, and can be a useful tool for dealing with tax debt where the individual is ineligible for Chapter 13. We handle individual Chapter 11 cases, and wrote a book on them, including the treatment of taxes. Chapter 11 may or may not be the right option for you, so consult with an attorney experienced in handling individual Chapter 11 cases to go over your options.
Your question is unclear. If all you are asking if chapter 11 exists (possibly for individual's such as yourself) then yes. I suggest you speak with a lawyer to see if chapter 11 is right for you.
