Which of the following compounds show strong H-bonding with water?
Correct answer: D. C2H5OH
- A. C2H6
- B. CH3Br
- C. CH3OCH3
- D. C2H5OH
Explanation
General solubility rule is 'like dissolves like'.So water can only be soluble in those compounds which show hydrogen .Ethanol (C2H5OH) has a highly electronegative element (oxygen) bonded to elements with low electronegativities (carbon and hydrogen) and so, is able to form hydrogen bonds with water.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
