JEE PYQ: P Block Elements Question 53
Question 53 - 2019 (10 Apr Shift 1)
The correct order of catenation is:
(1) C > Sn > Si $\approx$ Ge
(2) C > Si > Ge $\approx$ Sn
(3) Si > Sn > C > Ge
(4) Ge > Sn > Si > C
Show Answer
Answer: (2)
Solution
The catenation property among 14th group elements is based on bond enthalpy value. Bond enthalpy: C$-$C (348) > Si$-$Si (297) > Ge$-$Ge (260) $\approx$ Sn$-$Sn (240). Decreasing order of catenation is C > Si > Ge $\approx$ Sn.
