Consider the following mechanism: Cl2 ⇌ 2Cl
Cl+ CO ⇌ COCl
COCl + Cl2 ⇌COCl2 + Cl
2Cl ⇌ Cl2

Determine if each statement is true or false.

a. Cl is an intermediate and a catalyst.
b. COCI is the only intermediate
c. Cl is a catalyst
d. Both Cl and COCI are intermediates

d. Both Cl and COCI are intermediates.

Explanation:

Hey there!

In this case, according to the given mechanism:

Cl2 --> 2Cl

Cl+ CO --> COCl

COCl + Cl2 --> COCl2 + Cl

2Cl --> Cl2

We can see that the overall reaction, omits the presence Cl, COCl and the result is:

Cl2+CO-->COCl2

Which means d. Both Cl and COCI are intermediates.

Regards!

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
