Question

Which of the following pairs of compounds will not form H-bonds with each other?

• A. Ethanol-methanol
• B. Ethanol-water
• C. Chloroform-acetone
• D. Carbon tetrachloride-acetone

Answer 1

The correct option is D Carbon tetrachloride-acetone

$CC{l}_4$ and $(C{H}_3{)}_{2}C=O$ will not form H-bonds with each other. Both acetone and carbon tetrachloride are non-polar covalent compounds which are not miscible with each other and do not form hydrogen bonds whereas the others are polar and form H-bonds. In option C, the O of acetone and H of chloroform can form hydrogen bond but it is not that stable as other molecules with N,O and F.
