Question

At ordinary temperature and pressure chlorine is a gas, bromine a liquid, and iodine a solid. This is due to the fact that (A) the specific heat is in the order I2 > Br2 > Cl2 (B) the intermolecular forces in molecules of chlorine are the weakest and those in iodine are the strongest (C) the order of density is I2 > Br2 > Cl2 (D) the order of stability is I2 > Br2 > Cl2

Among the three halogens, the size decreases in the order I2 > Br2 > Cl2 and so the intermolecular forces of attraction also decrease in the same order. Therefore, Cl2 has the weakest and I2 has the strongest intermolecular forces of attraction.

Q. At ordinary temperature and pressure chlorine is a gas, bromine a liquid, and iodine a solid. This is due to the fact that

the specific heat is in the order $I_{2} > B r_{2} > C l_{2}$

the intermolecular forces in molecules of chlorine are the weakest and those in iodine are the strongest

the order of density is $I_{2} > B r_{2} > C l_{2}$

the order of stability is $I_{2} > B r_{2} > C l_{2}$

Among the three halogens, the size decreases in the order $I_{2} > B r_{2} > C l_{2}$ and so the intermolecular forces of attraction also decrease in the same order. Therefore, $C l_{2}$ has the weakest and $I_{2}$ has the strongest intermolecular forces of attraction.

Q. At ordinary temperature and pressure chlorine is a gas, bromine a liquid, and iodine a solid. This is due to the fact that

the specific heat is in the order I2​>Br2​>Cl2​

the intermolecular forces in molecules of chlorine are the weakest and those in iodine are the strongest

the order of density is I2​>Br2​>Cl2​

the order of stability is I2​>Br2​>Cl2​

Among the three halogens, the size decreases in the order I2​>Br2​>Cl2​ and so the intermolecular forces of attraction also decrease in the same order. Therefore, Cl2​ has the weakest and I2​ has the strongest intermolecular forces of attraction.
