How would each carbon atom in acetylene bond? Explain
a
Each carbon atom would share one pair of electrons with the other carbon atom and two pairs with each hydrogen atom.
b
Each carbon atom would share one pair of electrons with the other carbon atom and three pairs with each hydrogen atom.
c
Each carbon atom would share one pair of electrons with hydrogen and three pairs with the other carbon atom.
d
Each carbon atom would share one pair of electrons with hydrogen and one pair with the other carbon atom.
The correct answer is d. Each carbon atom in acetylene would share one pair of electrons with hydrogen and one pair with the other carbon atom.
Acetylene is a molecule with the chemical formula C2H2. It consists of two carbon atoms, each bonded to two hydrogen atoms, and sharing a triple bond with each other. The triple bond is made up of one sigma bond and two pi bonds.
In acetylene, each carbon atom has four valence electrons. To achieve a stable arrangement of electrons, each carbon atom forms four covalent bonds. One pair of electrons from each carbon atom is shared with a hydrogen atom, forming a single bond. The remaining pair of electrons on each carbon atom is shared with the other carbon atom, forming a double bond.
Therefore, each carbon atom in acetylene would share one pair of electrons with hydrogen and one pair with the other carbon atom. This arrangement allows each carbon atom to have a full valence shell with eight electrons (including the shared electrons) and satisfy the octet rule.
