Question

X and Y are two elements having similar properties which obey Newland’s Law of

Octaves. The minimum and the maximum number of elements in between X and Y

respectively are :

(A) 6 and 8

(B) 7 and 15

(C) 8 and 14

(D) 6 and 13​

Answer 1

The minimum and the maximum number of elements in between X and Y respectively are 6 and 13. (Option D)

• It is assumed that X and Y are two elements with comparable characteristics that adhere to Newland's Law of Octaves.
• Thus, according to Newland's rule of Octaves, those with comparable physical and chemical qualities come after each interval of seven elements, hence there are at least six elements between X and Y.
• This suggests that there are eight groupings of elements, with the ninth member having attributes identical to the first.
• As a consequence, the lowest and maximum number of elements between X and Y are 6 and 13, respectively.
• Option D is the right response.
