Well kjehladahl is a method for estimation of elements, Nitrogen I think, I dont remember well.

Ya I think Tarin is right
The Kjeldahl method is a method to determine the quantity of N in a cpd.
So I guess Kjeldahlising a Compound means either finding the quantity of N in it or carrying out the Kjeldahl method on the given cpd.
Post the question We may be able to help you better....
For more on the Kjeldahl method:

This method is basically used for quantitative analysis of organic compounds

You can never solve a problem on the level on which it was created.
When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity
Purpose of solving a problem is not simply to get the answer(the answer is only an evidence) but to develop your thinking ability |

It is used only for N not for all organic compounds.

kjeldahls methodis used to determine nitrogen content in organic compounds in which nitrogen is attached to cabron and hydrogen (bt not in azo,nitro and azoxy) principle:nitrogen is heated with conc sulphuric acid in copper sulphate which converts it into ammonium sulphate . this ammonium sulphate is treated with excess of alkali which decomposes to ammonia from which nitrogen content is calculated. catalyst used is coppersulphate and mercury . potassium sulphate is also added to raise the boiling point of sulphuric acid.
