Question

Which of the following orbital is non-directional?

• A. $s$
  
• B. $p$
  
• C. $d$
  
• D. $f$
  
  

Answer 1

The correct option is A $s$


Shape of $s,p,d$ orbitals are spherical, dumbbell, double dumbbell respectively and the shape of f orbital is quite complex.
Due to the spherical shape, ${}^{\prime }{s}^{\prime }$ orbitals are non directional.
