Solution

The correct option is D

Both (a) and (b)


Explanation for correct option

(a) 2s- orbital has one nodal surface.

  • To find the number of nodal surfaces, we use the formula
  • Nodes=n-1wherenisthenumberofshell
  • Here it is given that n=2
  • So, number of nodal surfaces =2-1=1
  • Hence, the option (a) 2s- orbital has one nodal surface is correct.

(b) For 2px orbitals yz is the nodal plane.

  • Nodal plane will be perpendicular to the xaxis.
  • Hence 2px orbitals will have yz as the nodal plane.
  • Hence option (b) For 2px orbitals yz is the nodal plane is correct.

(d) Both (a) and (b)

  • Since both option (a) and (b) is correct
  • And option (d) says both (a) and (b) are correct.
  • Hence, (d) Both (a) and (b) is the correct option

Explanation for incorrect option

(c) Electron density in the xy-planein3dx2-y2 orbital is zero.

  • The orbital lobes of 3dx2-y2 will be along x and y axis.
  • So electron density is not zero in the xy-planein3dx2-y2.
  • Hence option (c) Electron density in the xy-planein3dx2-y2 orbital is zero is incorrect.

Hence, option (d) Both (a) and (b) is the correct option.
