Question

part a which element do organic compounds always contain? ○ n ○ c ○ h ○ o

Explanation:

Organic compounds are defined as compounds that always contain carbon (C). While many organic compounds also contain hydrogen (H), oxygen (O), or nitrogen (N), carbon is the essential element that all organic compounds must have. For example, methane ($CH_4$) has C, and even compounds like carbon tetrachloride ($CCl_4$) (which has no H, O, or N) are organic because they contain C. So the element organic compounds always contain is C.

Answer:

B. C
