Question

Carbon, the first member of group `14`, shows an anomalous behavior because of
`(i)` its exceptinally small atomic and ionic size
`(ii)` its higher electronegativity
`(iii)` its higher ionization enthalpy
`(iv)` the absence of vacant `d`-orbitals in the valence shell
A. `(i), (ii)`
B. `(ii), (iii)`
C. `(iii), (iv)`
D. `(i), (ii), (iii), (iv)`

Answer 1

Correct Answer - D
As a result of these factors, the element `C` exhibits strong tendency to catenate, strong ability to form `p_(pi) - p_(pi)` multiple bonds, and shows a maximum covalency of `4` in its compounds.
