Which formula represents a hydrocarbon

This question is incomplete. Here is the complete question:

Which formula represents a hydrocarbon?

(1) CH3I

(2) CH3NH2

(3) CH3CH3

(4) CH3OH

The correct answer is option (3) CH3CH3 .

Explanation:

Hydrocarbon is an organic compound and as we can see in its formula, it is composed of hydrogen (H) and carbon (C).

Each carbon has 4 electrons, it is for this reason that it will have to make four bonds for the union to be stable, and since these bonds in carbon are generated in an easy and strong way, this will allow thousands of types to be generated of hydrocarbons.

There are different chains that these atoms can form:

In turn, hydrocarbons can be classified as aliphatic or aromatic.

Given this information we can say that the correct answer is option C.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

i think it is d. e because the next one is igneous.
