# Why is disodium acetylide considered as an organic compound? [duplicate]

Even though disodium acetylide ($\ce{C2Na2}$) has carbon bonded with metal atoms and does not have a single carbon hydrogen bond in it, why is it considered as an organic compound? If this is an organic compound then why don't we call $\ce{CO2}$ an organic because it can also be produced from reacting organic compounds?

• Organic compounds are those which are studied in the departments of organic chemistry for historical reasons. There is no deeper meaning behind that. – Ivan Neretin Mar 7 '17 at 8:48
• From Clayden's Organic Chemistry, chapter 1, page 12: "So where does inorganic chemistry end and organic chemistry begin? ... The answer is that we don’t know and we don’t care." – Don_S Mar 7 '17 at 9:06
