Question

Which of the following lists contains common heteroatoms found in organic molecules?

a) C, H, O, N
b) C, H, O, F
c) C, H, O, P
d) C, H, O, S

Answer 1

The common heteroatoms in organic molecules include oxygen, nitrogen, sulfur, phosphorus, and halogens. The correct answer from the provided list is (d) C, H, O, S.

Step-by-step explanation:

The question pertains to the identification of common heteroatoms found in organic molecules. Heteroatoms are atoms within a molecule that are not carbon (C) or hydrogen (H). In typical organic chemistry contexts, the most common heteroatoms include elements such as oxygen (O), nitrogen (N), sulfur (S), phosphorus (P), and the halogens (F, Cl, Br, I). Therefore, the correct answer from the provided options would be (d) C, H, O, S, which includes sulfur as a common heteroatom alongside carbon, hydrogen, and oxygen.

In organic compounds, these heteroatoms can be bonded in various ways, including single bonds with sp³ hybridization or double bonds with sp² hybridization, and can significantly affect the physical and chemical properties of the compounds they are part of.
