Identify the correct statement (s) from the following:
(i) The catentiaon property of group 14 elements decreases from carbon to tin.
(ii) Fullerence `(C_(60))` has 20 five-membered carbon rings and 12 six-membered carbon rings.
(iii) `SiO_(2)` is soluble in Conc.NaOH.

A

Only iii

B

`I,iii`

C

`I,ii`

D

`ii,iii`

Text Solution

Verified by Experts

The correct Answer is:
B
(i) For carbon atoms, bonding is strong due to their small size. Thus maximum catenation From carbon to tin in group 14 elements, the atom size increases, thus result in low bonding and decreased catention.
(ii) Fullerence `(C _(60))-20` sin-membered carbon rings
-12 five-membered carbon rings
(iii) `2NaOH + SiO_(2)` is Soluble in conc NaOH
