JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
Which of the following statements are not correct? \(A.\) The electron gain enthalpy of \(F\) is more negative than that of \(Cl\) \(B.\) Ionization enthalpy decreases in a group of periodic table \(C.\) The electronegativity of an atom depends upon the atoms bonded to it. \(D.\) \(Al _2 O _3\) and \(NO\) are examples of amphoteric oxides. Choose the most appropriate answer from the options given below:
- A \(A,B,C\) and \(D\)
- B \(A,C\) and \(D\) Only
- C \(B\) and \(D\) Only
- D \(A,B\) and \(D\) Only
Answer & Solution
Correct Answer
(B) \(A,C\) and \(D\) Only
Step-by-step Solution
Detailed explanation
Electronegativity of an element depends on the atom with which it is attached. \(NO =\text { neutral oxide }\) \(Al _2 O _3=\text { amphoteric oxide }\)
