The compound ethylene (C2H4) is represented by this diagram. Two C's connected by two lines. Each C is connected by single lines to 2 H's. What statement best describes the arrangement of the atoms in an ethylene molecule? Each carbon atom shares two electrons with one hydrogen atom and also shares two electrons with the other carbon atom. Each carbon atom shares four electrons with one hydrogen atom and also shares four electrons with the other carbon atom. One electron is shared between each hydrogen atom and the carbon atom bonded to it, and two electrons are shared between the carbon atoms. Two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms
Answers
Answer:
A. A carbon atom forms a covalent bond with other atoms. In this bond the two atoms share electrons.
Explanation: A carbon atom forms a covalent bond with other atoms
because its outer shell is half full as shown in the figure below:

In the covalent bond, sharing of electrons takes place. For example:
CH4

B. All the carbon bonds in a saturated hydrocarbon share electrons.
Explanation: The hydrocarbons having only single bonds between carbon atoms are called saturated hydrocarbons. Saturated
form covalent bond (by sharing of electrons)
C. At least one carbon bond in an unsaturated hydrocarbon is
double.
Explanation: Some hydrocarbons have a multiple bond between two carbon atoms. A multiple bond can be a double bond or a triple
bond. Hydrocarbons having at least one multiple bond are called unsaturated hydrocarbons.
For example, ethene
D. Carbon is the essential element in all the organic compounds.
Explanation: A carbon atom exhibits a characteristic property. It can form a chain of carbon atoms by forming covalent bonds with
other carbon atoms. Hence, it is the most essential element in the organic compounds.
E. The element hydrogen is present in most organic compounds.
Explanation: Along with carbon, the element hydrogen is also included in most organic compounds.
