Question:

$\text{The incorrect order of electronegativity is :}$

Options:

1. $\text{Cl} > \text{S} > \text{P} > \text{Si}$
2. $\text{Si} > \text{Al} > \text{Mg} > \text{Na}$
3. $\text{F} > \text{Cl} > \text{Br} > \text{I}$
4. $\text{None of the above.}$ (Correct)

Solution:

$\text{HINT: Electronegativity don't have any exceptional trend.}$\n\n$\text{Explanation:}$\n\n$\text{In the period, from left to right electronegativity increases.}$\n\n$\text{14} \quad \text{15} \quad \text{16} \quad \text{17}$\n\n$\text{Si} \quad \text{P} \quad \text{S} \quad \text{Cl}$\n\n$\text{Na} \quad \text{Mg} \quad \text{Al} \quad \text{Si}$\n\n$\text{In periodic table general trend of electronegativity is :}$\n\n$\text{From left to right = increase and from top to bottom = Decrease}$\n\n$\text{F} > \text{Cl} > \text{Br} > \text{I}$\n\n$\text{All have correct order of electronegativity.}$\n\n$\text{Hence option 4 is correct.}$
