Which of the following options represents the correct Lewis structure for methane
(CH₄)?
-
A.
A carbon atom bonded to four hydrogen atoms with single bonds
-
B.
A carbon atom bonded to one hydrogen atom with a double bond
-
C.
A carbon atom bonded to two hydrogen atoms with double bonds
-
D.
A carbon atom bonded to four hydrogen atoms with triple bonds
Correct Answer:
A. A carbon atom bonded to four hydrogen atoms with single bonds
Explanation:
Methane (CH4) consists of a central carbon atom that shares its four valence electrons with four individual hydrogen atoms. Since hydrogen only requires two electrons to achieve a stable outer shell and carbon requires eight, they form four covalent single bonds. This arrangement completes the octet for carbon and the duet for each hydrogen, making a carbon atom bonded to four hydrogen atoms with single bonds the correct Lewis structure.
