Question

For each item: classify organic or inorganic. NaCl: . phenol (C6H6;O): . C2H6: . Ca3(PO4)2: . formaldehyde (CH20): . MgCO3: .

Answer 1

NaCl - inorganic
Phenol - organic
C2H6 - organic
Ca3(PO4)2 - inorganic
CH2O - Organic
MgCO3 - Organic
Basically, if it has Carbon (other than a few) it is organic.

Answer 2

Explanation:

It is known that compound that contain carbon atom and hydrogen atom which are combined together are known as organic compounds. Carbon atom is the main element present in an organic compound.

For example, $C_{6}H_{6}$ is an organic compound.

Whereas compounds that does not contain carbon atom are known as inorganic compounds.

Thus, we can conclude that given compounds are classified as follows.

Organic compounds : $C_{6}H_{6}$, $C_{2}H_{6}$, $CH_{2}O$, and $MgCO_{3}$.

Inorganic compounds : $Ca_{3}(PO_{4})_{2}$.
