Hydrogen bond plays a vital role in determining substance properties and structure. Which of the following may not an example?

(a) Proteins

(b) Nucleic acids

(c) Methane molecule

(d) Water

This question was addressed to me during an interview for a job.

Enquiry is from States of Matter in chapter States of Matter of Chemistry – Class 11

Answer 1

Right choice is (c) Methane molecule

To explain I would say: As per the above statement, substance properties and structure is determined as per the hydrogen bond present in them, but in a methane molecule, there is no hydrogen bond. So it may not be an example.
