Iodine, I2(s), is more soluble in dichloromethane, CH2Cl2(l), than water because:
Georgia [21]

Answer:

A. the intermolecular forces are similar in both dichloromethane and iodine.

Explanation:

Solubility is determined by the principle , "like dissolves like" .

i.e. , if a compound is polar then it will dissolve in a polar compound only , and

if a compound is non - polar then it will dissolve in a non - polar compound only .

As,

Non polar compounds , have similar interaction , and hence gets dissolved , and similarly ,

polar compounds have similar dipole - dipole interaction , and hence gets dissolved .

From the question ,

Iodine, I₂(s), is more soluble in dichloromethane, CH₂Cl₂(l) , as both are non - polar in nature and hence due to similar interaction , are soluble .

Water is polar in nature and therefore less soluble in Iodine, I₂(s) .
