Question

The Van der Waals radii of $O,N,Cl,F$ and $Ne$ increases in the order?

• A. $N,F,O,Ne,Cl$
• B. $N,O,F,Ne,Cl$
• C. $F,O,Ne,N,Cl$
• D. $F,Cl,O,N,Ne$

Answer 1

The correct option is C

$F,O,Ne,N,Cl$

Van der Waals radius decreases along a period from left to right due to increase in nuclear charge and then increases at noble gasses.

Chlorine being the element from the third period and rest from the second period has the largest size.

The van der Waal's radii for the afore mentioned elements are:
$N$- 155 pm
$O$- 152 pm
$F$- 147 pm
$Ne$- 154 pm
$Cl$- 175 pm
