a. $P-O$

b. $N-F$

c. $O-Cl$

d. $S-Cl$

e. $P-F$

Step-by-Step Solution

Answer

a. The dipole arrow of  $P-O$ is.

b. The dipole arrow of  $N-F$ is .

c. The dipole arrow of  $O-Cl$ is.

d. The dipole arrow of  $S-Cl$ is

e. The dipole arrow of  $P-F$ is.

Part (a) step 1: Given Information

We need to find the dipole arrow of $P-O$.

Part (a) step 2: Explanation

Here,

Consider bond is $P-O$.

The electronegativity of $P$ is $2.1$ and the electronegativity of $O$is $3.5$  . Therefore, the arrow should be pointing towards $O$.

Here, the dipole arrow is shown below. 

Part (b) step 1: Given Information

We need to find the dipole arrow of $N-F$.

Part (b) step 2: Explanation

Here,

Consider bond is $N-F$.

The electronegativity of $N$ is $3.0$ and the electronegativity of $F$ is $4.0$ . Therefore , the arrow should be pointing towards $F$.

Here, the dipole arrow is shown below. 

Part (c) step 1: Given Information

We need to find the dipole arrow of $O-Cl$.

Part (c) step 2: Explanation

Here,

Consider bond is $O-Cl$

The electronegativity of $Cl$ is $3.0$ and the electronegativity of $O$ is $3.5$ . Therefore  the arrow should be pointing towards $O$.  

Here, the dipole arrow is shown below. 

Part (d) step 1: Given Information

We need to find the dipole arrow of $S-Cl$.

Part (d) step 2: Explanation

Here,

Consider bond is $S-Cl$ 

The electronegativity of $S$ is $2.5$ and the electronegativity of $Cl$ is $3.0$ . Therefore , the arrow should be pointing towards $Cl$.

Here, the dipole arrow is shown below. 

Part (e) step 1: Given Information

We need to find the dipole arrow of $P-F$.

Part (e) step 2: Explanation

Here,

Consider bond is $P-F$.

The electronegativity of $P$ is $2.1$ and the electronegativity of $F$ is $4.0$ . Therefore, the arrow should be pointing towards $F$.

Here, the dipole arrow is shown below.
