Question

how many sigma bond and paai bond are C2H2

Answer 1

One c-c sigma bond and two c-c pi bond

Answer 2

$\textbf{ANSWER}$

____________________

C2H2 has triple bond between carbon and carbon and each carbon has a single bond with hydrogen so four bonds of carbon are completed

Now question is how many of these bonds are sigma and how much are pii .

So first of all u should be aware of sigma and pii bonds

$\textbf{SIGMA BOND }$

The bond formed by the linear overlap of atomic orbitals .

$\textbf{Pii BOND }$

The bond that is formed by the side wise overlap of atomic orbitals .

In C2H2 carbon has triple bond with the other carbon , here the first bond formed is sigma while the other two are pii bonds . and ech carbon has one sigma bond with hydrogen , So total there are :-

3 Sigma bonds

2 Pii bonds
