You said the one with C-H bonds are said to be organic compounds but in urea which is NH2CONH2 there is no C-H bond but it is considered as an organic comp. Next you said organic comp. doesn't form salts while inorg. comp. can form but now a days many salts of organic compounds are known. Thirdly you told that org. com. are formed in living beings but seeing a comp how can we predict that the given comp. is formed in living beings? Please tell me the correct method to identify an organic compound.

An organic compound is any member of a large class of chemical compounds whose molecules contain carbon. A few types of carbon-containing compounds such as carbonates, simple oxides of carbon and cyanides, as well as the allotropes of carbon such as diamond and graphite, are considered inorganic. 

 

The "C-H" definition excludes compounds which are historically and practically considered to be organic. Some of them lacking C-H bond and yet considered organic are urea, oxalic acid, benzenehexol, mesoxalic acid, and carbon tetrachloride.
