Question

which of the following is an organic molecule? multiple choice
salt (nacl)
sucrose (c$_{12}$h$_{22}$o$_{11}$)
none of these choices are correct.
hydrochloric acid (hcl)

Explanation:

Organic molecules typically contain carbon - hydrogen bonds (and are based on carbon chains/structures, with some exceptions like CO₂, but generally, compounds with C - H are organic).

• Salt (NaCl) is an ionic compound with sodium and chloride ions, no carbon, so not organic.
• Hydrochloric acid (HCl) is an inorganic acid with hydrogen and chlorine, no carbon, so not organic.
• Sucrose ($\ce{C_{12}H_{22}O_{11}}$) has carbon, hydrogen, and oxygen, and is a carbohydrate (a type of organic molecule) with carbon - hydrogen bonds.

Answer:

B. Sucrose ($\ce{C_{12}H_{22}O_{11}}$)
