Question

Assertion : the nature of chemical bonding HF molecule is ionic in nature
Reason: the difference in electronegativity values H and F is 1.9

Answer 1

Answer:

A and R are correct ,R explains A.

Explanation:

According to Pauling scale, if the electronegativity is greater than 1.7 , the bond is considered to be ionic.

Electronegativity of H = 2.1

Electronegativity of F = 4.0

we get, Electronegativity of HF = 6.1
