Which of the following compounds has a linear shape?

Which of the following compounds has a linear shape?

Step 1: Understand what a linear shape means in chemistry. A linear shape means that the atoms are arranged in a straight line.
Step 2: Identify the compound in question, which is C2H2 (ethyne).
Step 3: Look at the structure of C2H2. It consists of two carbon atoms and two hydrogen atoms.
Step 4: Check the hybridization of the carbon atoms in C2H2. In this case, the carbon atoms undergo sp hybridization.
Step 5: Recognize that sp hybridization leads to a linear arrangement of atoms because it forms a bond angle of 180 degrees.
Step 6: Conclude that since C2H2 has sp hybridization, it has a linear shape.
