JEE Main Chemistry question

The tendency for catenation in Group 14 elements varies in the order [DCE 2005]

(A)C \gg Si > Ge = Sn > PbCorrect
(B)C \ll Si < Ge = Sn < Pb
(C)C \gg Si = Ge < Sn < Pb
(D)C \gg Si = Ge < Sn > Pb

Answer: (A)

Solution

Catenation (self-linking) ability depends on bond strength, which falls steeply down group 14 as atomic size increases and orbital overlap weakens, so carbon shows by far the greatest catenation,
