Which statement about organic compounds is true?
A compound that contains oxygen and hydrogen is organic if the compound lacks carbon.
A compound that a living organism requires for survival is considered to be organic.
An organic compound typically has at least one carbon–hydrogen or carbon–carbon bond.
A naturally‑occurring compound is organic, whereas a synthetic compound is inorganic.

An organic compound typically has at least one carbon–hydrogen or carbon–carbon bond.

Explanation:

It is true that organic compounds have one or more carbon atoms covalently bound to other atoms like hydrogen, oxygen etc

Examples of organic compounds include:

- methane (CH3)

- ethanol (C2H5OH)

In methane, carbon–hydrogen bond is present; while in ethanol both one carbon–hydrogen and carbon-carbon bond is present.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the answer is b & c i believe : )
