Answer 1

The correct answer is D.

In group A, CaSO4 is not organic; in group B, CaCl2 is not organic; in group C, Ca3(PO4)2 is not organic.

Hope this helps~

Answer 2

Answer;

D. C6H6, C2H5OH, C6H5CH3, and C3H5(NO3)3.

Step-by-step explanation;

-Organic compound are chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen, like the examples above in choice D. . Inorganic Compounds on the other hand, are compounds made from any elements except those compounds of carbon, such as CaSO4, CaCl2 and Ca3(PO4)2 in A, B and C respectively.
