Answer:

65.7g of chlorobenzene is expected to be produced.

Explanation:

The reaction equation is:

[tex]C_{6} H_{6} (l) + Cl_{2} (g)[/tex] → [tex]C_{6} H_{5}Cl (s) + HCl(g)[/tex]

Mole ratio of C6H6 to CH5Cl is 1 : 1: that is for every 1 mole of benzene used in the reaction, 1 molee of chlorobenzene is produced.

1 mole of C6H6 - 78.11 g

?? mole of C6H6 - 45.6 g  ⇒ [tex]\frac{45.6}{78.11}[/tex] = 0.58 moles used in reaction

Consequently,

1 mole of chlorobenzene - 112.56 g

0.58 moles of chlorobenzene = 112.56 × 0.58

= 65.7g

The theoretical yield should be 65.7g.

Calculation of the theoretical yield:

The reaction equation is

C6H6(l) + Cl2(g) → C6H5Cl(s) = HCl (g)

Here

The mole ratio of C6H6 to CH5Cl is 1: 1 i.e. every 1 mole of benzene used in the reaction, 1 moles of chlorobenzene is produced.

Since 1 mole of C6H6 - 78.11 g

So, for 45.6g, it should be

= 45.6/78.11

= 0.58 moles

Now

1 mole of chlorobenzene - 112.56 g

So, for 0.58 moles it should be

= 112.56 × 0.58

= 65.7g
