Q. Hydrogen bonding is NOT present in:
हाइड्रोजन बंधन मौजूद नहीं है:
Explanation
Hydrogen bonding occurs when hydrogen is bonded to highly electronegative atoms like N, O, or F.
Water (H₂O), ethanol (C₂H₅OH), and ammonia (NH₃) all contain O or N and can form H-bonds.
Methane (CH₄) has C–H bonds, but carbon is not electronegative enough, so no hydrogen bonding occurs.
