Question

which of the following substances is more likely to dissolve in CH3OH? a) CCl4 b) CH3CH2OH c) N2 d) H2

Answer 1

The correct answer is option 'B' that means Ethyl alcohol .

Reason:

The methanol is very good polar solvent. so there is chance of dissolve to only that molecules those are polar in nature or have same ionic nature.

Here from the above options

​ which is nonpolar molecule. It has no dipole moment.

which is nonpolar molecule and has no resultant dipole moment. Both N atom of N₂ will cancel their dipole moment to give net zero dipole resultant because of their equal electronegativity.

is nonpolar molecule. Because both hydrogen atoms have equal electronegativity to produce zero dipole moment.

But in the case of Ethyl alcohol , it is a polar molecule and has net dipole moment. Hence it can be dissolved in Methyl alcohol in any amount of water.
