What is the hybridization of the carbon atoms in ethyne (C2H2)?
Correct Answer: sp
Step 1: Identify the molecular formula of ethyne, which is C2H2.
Step 2: Understand that each carbon atom in ethyne is bonded to one hydrogen atom and is involved in a triple bond with the other carbon atom.
Step 3: Recognize that a triple bond consists of one sigma bond and two pi bonds.
Step 4: Determine the number of regions of electron density around each carbon atom. In this case, there are two regions: one from the sigma bond with hydrogen and one from the triple bond with the other carbon.
Step 5: Use the VSEPR theory to find the hybridization. Two regions of electron density correspond to sp hybridization.
Step 6: Conclude that the carbon atoms in ethyne are sp hybridized.
