Hello, Can some one please tell me if B is the correct answer?

Thank You

Which one of the following groups of chemical compounds is composed entirely of organic compounds?
A. C2H4O, CH2O, CaSO4, C3H5(OH)3
B. C6H6, C2H5OH, C6H5CH3, C3H5(NO3)3
C. C2H2, CH4, CaCl2, CaCN2
D. Ch3OCH3, Ca3(PO4)2, CO2, H2CO3

Yes, it is B

Collect organic compounds:

a) NaOH; b) Na2CO3; c) CH4; d) C2H2; e) CO 2; f) C2H5OH

To determine which group of chemical compounds is composed entirely of organic compounds, we need to understand what organic compounds are. Organic compounds are compounds that contain carbon atoms, combined with other elements such as hydrogen, oxygen, nitrogen, sulfur, and more. They are typically found in living organisms or are derived from them.

Let's analyze each group of compounds provided in the options:

A. C2H4O, CH2O, CaSO4, C3H5(OH)3
Only the first two compounds (C2H4O and CH2O) contain carbon atoms. CaSO4 and C3H5(OH)3 are inorganic compounds because they lack carbon atoms. This option is not composed entirely of organic compounds.

B. C6H6, C2H5OH, C6H5CH3, C3H5(NO3)3
All compounds in this group (C6H6, C2H5OH, C6H5CH3, C3H5(NO3)3) contain carbon atoms. Therefore, this group is composed entirely of organic compounds.

C. C2H2, CH4, CaCl2, CaCN2
Only the second compound (CH4) contains carbon atoms. C2H2, CaCl2, and CaCN2 are inorganic compounds because they lack carbon atoms. This option is not composed entirely of organic compounds.

D. Ch3OCH3, Ca3(PO4)2, CO2, H2CO3
The first compound (Ch3OCH3) contains carbon atoms, whereas the other compounds (Ca3(PO4)2, CO2, and H2CO3) do not. This option is not composed entirely of organic compounds.

Therefore, the correct answer is option B.
