The $F_2$ molecule is formed by which of the following?

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 $(CH_2=CH-CH=CH_2)$

Which orbitals on overlapping will form $\sigma$ and $\pi$ bond in $C=C$ of alkene? Explain.

The nodal plane in the $\pi-$bond of ethene is located in

Number of $\sigma$ and $\pi$ bonds present in $CH_3-CH=CH-C\equiv CH$ are

The strongest bond is formed when atomic orbitals undergo:
