Which type of bond is formed by the linear overlap of two hybrid orbitals,each containing one electron,associated with two different atoms?

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

How many $\sigma$ and $\pi$ bonds are present in $CH_3COOH$?

Calculate the ratio of $\sigma$ and $\pi$ bonds for the following compounds and determine the correct order:
$A$: Tetracyanomethane $(C(CN)_4)$
$B$: Carbon dioxide $(CO_2)$
$C$: Benzene $(C_6H_6)$
$D$: $1, 3$-Butadiene $(CH_2=CH-CH=CH_2)$

How and when is a $\pi$-bond formed by the overlapping of orbitals?

Which of the following contains $p\pi - p\pi$ bonding?
