It is insoluble
no
yes like disolve slikje. both are non polar substances as cyclohexane is a natural substance. I2 has equal distribution of e- on both sides.
The formula for methylene chloride is CH2Cl2
Iodine (I2) reacts with iodide (I-) to form triiodide ion (I3-). Although I2 is insoluble in water, I3-is very soluble, so adding KI will pull I2into solution is I3-.
It is insoluble
no
yes, but not in cH2CL2
Caffeine is more soluble in acetone then methylene chloride (CH2CL2)
C is not but d, e and folic acid are
Iodine itself, I2 is not very soluble in water. However, the solubility of iodine can be greatly increased by adding potassium iodide to the reaction. The potassium iodide is broken apart into K+ and I-. The potassium ion is then dissolved into the water, and the iodine ion reacts with the I2 to form I3-. This I3- molecule is soluble in water. Therefore, the solubility is relative because I2 is not very soluble, but I3- is soluble, and both are made of nothing but iodine. Hope this helps.

ccl4 will dissolve better in water because likes dissolves likes, H2O is non-polar an CCL4 is also non polar where as ch2cl2 is polar(different to water) there for it wont dissolve in water but CCL4 will^^This is not true: water is polar. Therefore, since CCl4 is non-polar, and CH2Cl2 is polar, and like dissolves like, CH2Cl2 is more soluble.
H2O is very slightly soluble in CH2CL2 but H2O is hydrophillic and CH2Cl2 is hydrophobic therefore the two molecules dont react or bond properly resulting in a two phase solution of an aquous and organic layer containg a very small percentage of the H2O.
