Assertion (A) : Actinoids form relatively less stable complexes as compared to lanthanoids.
Reason (R ): Actinoids can utilise their 5f - orbitals along with 6d - orbitals in bonding but lanthanoids do not use their 4f - orbital for bonding.

A

both (A) and (R ) are true, and (R ) is the correct explanation of (A).

B

both (A) and (R ) are true, but (R ) is not the correct explanation of (A).

C

(A) is false but (R ) is true.

D

(A) and (R ) both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Copper Assertion : Actinoids form relatively more stable complexes as compared to lanthanoids (because the former have high charge density).

Each question contains statements given in two columns which have to be matched. Statements (a,b,c,d) in column I have to be matched with statements (p,q,r,s) in column II. If the correct match are a-p, s, b-r c-p, q. and d-s, then the correctly bubbled 4x4 matrix should be as follows: figure Column I, a) If int(2^x)/(sqrt(1-4^x))dx=ksin^(-1)(f(x))+C , then k is greater than, b) If int((sqrt(x))^5)/((sqrt(x))^7+x^6)dx=aln(x^k)/(x^k+1)+c , then a k is less than, c) If int(x^4+1)/(x(x^2+1)^2)dx=kln|x|+m/(1+x^2)+n , where n is the constant of integration, then m k is greater than, d) If int(dx)/(5+4cosx)=ktan^(-1)(mt a n x/2)+C , then k//m is greater than, COLUMN II p) 0 q) 1 r) 3 s)4
