Question

electronic configuration and anomalous behavior and trends​

Answer 1

Answer:

Carbon additionally has an extraordinary capacity to shape pp – pp multiple bonds with itself and with different molecules which have smaller size and high electro negativity. Couple of illustrations are: C = C, C° C, C = O, C = S and C° N. Heavier elements don't shape pp – pp bonds in light of the fact that their nuclear orbitals are too vast and diffuse to have viable overlapping.

Carbon atoms tend to interface with another through covalent bonds to shape chains and rings. This property is termed as catenation. This is on account of C – C bonds are extremely solid. This chain can be as large as to contain aggregate of 70-80 carbon. This offer ascent to extremely complex compounds having straight carbon chain, extended carbon chain and ring. The carbon compounds having just single bond are termed as saturated hydrocarbons while compounds having double or triple bond are termed as unsaturated hydrocarbons. As we move down the group the size increases and electro negativity diminishes and in this way, propensity to show catenation also decreases. This can be clearly observed from bond enthalpy values. The catenation order is C >> Si > Ge » Sn.
