Per NCERT §4.9, a HYDROGEN BOND forms when a hydrogen atom is between which two atoms?
AHydrogen between two highly electronegative atoms — F, O, or N (e.g. H bonded to F covalently, H-bonded to F of next molecule)
BH between two metal atoms
CH between two C atoms
DH between H and Cl
Answer & Solution
Correct answer: A. Hydrogen between two highly electronegative atoms — F, O, or N (e.g. H bonded to F covalently, H-bonded to F of next molecule)
Per NCERT §4.9, H-bond requires H covalently bound to F/O/N + attracted to another F/O/N. Weaker than covalent.
