The number of sigma $(\sigma)$ and pi $(\pi)$ bonds present in benzene respectively are:

What is the total number of $\pi$ bonds in the compound $CH_2=CH-CH=CH-COOH$?

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

The $d_{xy}$ orbital can form a $\pi$ bond with another $d_{xy}$ orbital along which axis?

$\pi$ bond is formed by:

Match the orbital overlap figures shown in List-$I$ with the description given in List-$II$ and select the correct answer using the code given below the lists.
List-$I$:
$P$. Two $d$-orbitals overlapping axially with same phase.
$Q$. $A$ $p$-orbital and a $d$-orbital overlapping laterally with same phase.
$R$. $A$ $p$-orbital and a $d$-orbital overlapping laterally with opposite phase.
$S$. Two $d$-orbitals overlapping axially with opposite phase.
List-$II$:
$1$. $p-d$ $\pi$ antibonding
$2$. $d-d$ $\sigma$ bonding
$3$. $p-d$ $\pi$ bonding
$4$. $d-d$ $\sigma$ antibonding
Codes: $P \quad Q \quad R \quad S$
