Urea

Vedclass · Answer

(B) hydrocarbon is an organic compound consisting entirely of hydrogen and carbon atoms. $1$. Benzene $(C_6H_6)$ is a hydrocarbon. $2$. Urea $(NH_2CONH_2)$ contains nitrogen and oxygen in addition to carbon and hydrogen,so it is not a hydrocarbon. $3$. Ammonium cyanate $(NH_4OCN)$ is an inorganic compound. $4$. Phenol $(C_6H_5OH)$ contains an oxygen atom,so it is not a hydrocarbon. Since the question asks for a substance that is not a hydrocarbon,both $B$,$C$,and $D$ fit the criteria. However,in the context of introductory chemistry,$Urea$ $(NH_2CONH_2)$ is the most common example cited as a non-hydrocarbon organic compound. Given the options,$B$ is the most appropriate answer.
