Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

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 ....for ques 7👆

ques 6

for ques 8... you can also correlate this without data...as down the group EN decreases and along the period it increases...so F is most electronegative atom and EN value of K is less than Li and Na...so KF has the maximum EN difference

7)The size of the d orbitals in Si, P, S and Cl follows the order. Soln: Size of d-orbitals decrease with decrease in size of element. The decreasing order of size is Si > P > S >C 9) from left to right electronegativity increases out of al,s sulphur more electronegativity ca,as as has more electronegativity from these two trends option B correct
