What is the number of $\sigma$ and $\pi$ bonds in the resonance structure of benzene?

Explain $\sigma$ bond formed by $s-s$,$s-p$ and $p-p$ overlapping.

Which type of overlapping results in the formation of a $\pi$ bond?

$A$ molecule $(X)$ has $(i)$ four sigma bonds formed by the overlap of $sp^2$ and $s$ orbitals,(ii) one sigma bond formed by $sp^2$ and $sp^2$ orbitals,and (iii) one $\pi$ bond formed by $p_z$ and $p_z$ orbitals. Which of the following is $X$?

State the number of $\sigma$ and $\pi$ bonds in the following molecules:
$(a)$ $C_2H_2$
$(b)$ $C_2H_4$

What is the total number of sigma $(\sigma)$ and pi $(\pi)$ bonds in the following molecules?
$(a)$ $C_{2}H_{2}$
$(b)$ $C_{2}H_{4}$
