Paper: CSIR NET June 2012 · Subject: Inorganic Chemistry · Chapter: Chemical Bonding · Topic: Chemical Bonding – General · Marks: 2 · Difficulty: Easy
The size of the d orbitals in Si, P, S and Cl follows the order.
(a)Cl > S > P > Si
(b)Cl > P > S > Si
(c)P > S > Si > Cl
(d)Si > P > S > Cl
Answer
Answer (as printed): D
Explanation
Size of d-orbitals decrease with decrease in size of element. The decreasing order of size is Si > P > S > Cl. Therefore decreasing order of size of d-orbitals is Si> P > S >Cl. -
