Answer

Explanation:

Step1: Calculate valence - electrons

Carbon has 4 valence electrons and hydrogen has 1 valence electron. For $C_2H_2$, the total number of valence electrons is $2\times4 + 2\times1=10$.

Step2: Draw the Lewis - structure

The Lewis - structure of $C_2H_2$ is $H - C\equiv C - H$. There is a triple bond between the two carbon atoms and a single bond between each carbon and hydrogen atom.

Step3: Check for resonance

Resonance occurs when there are multiple valid Lewis - structures with the same arrangement of atoms but different arrangements of electrons. In the case of $C_2H_2$, there is only one valid Lewis - structure. So, there is no resonance.

Answer:

no resonance
