Question

question 3 (1 point)
which of the following is an organic compound?
a. $h_{2}o$ c. $co_{2}$
b. $mgo$ d. $ch_{4}$

Explanation:

Organic compounds are defined as compounds that contain carbon - hydrogen bonds (except for a few exceptions like carbonates, carbides, and some simple carbon - containing molecules like \(CO\), \(CO_2\)).

• \(H_2O\) (water) does not contain carbon, so it is not an organic compound.
• \(MgO\) (magnesium oxide) contains magnesium and oxygen, no carbon, so it is not an organic compound.
• \(CO_2\) (carbon dioxide) is a simple carbon - containing molecule but does not have carbon - hydrogen bonds and is classified as an inorganic compound.
• \(CH_4\) (methane) has carbon - hydrogen bonds (\(C - H\) bonds) and is an organic compound.

Answer:

D. \(CH_4\)
