Q. Strongest hydrogen bond is present in
A) [image:4_image22.emf]
B) [image:4_image23.emf]
C) [image:4_image24.emf]
D) [image:4_image25.emf]
Explanation
(a)
More the difference in electronegativity of atoms, stronger will be the hydrogen bond. $\because$ Electronegativity difference between H and F is highest.
(∵F has highest electronegativity)
$\because$ $F - H - - - - - O$ hydrogen bond is strongest.
