In C, Si Ge and Sn the decreasin order of cetanation is

The order of catenation of C,Si,Ge,Sn is

Arrange the followingg hydrogen halides in order of their decreasin reactivity with propene.

Some statements are given regarding IVA group elements A) Order of Electronegativity : C> Si = Ge=Sn B) Order of Ionisation potential : C> Si > Ge > Pb > Sn C) Order of Melting point : C> Si > Ge > Pb > Sn Correct orders of the above

Explain the following order of first ionisation enthalpies (Delta_iH_1) ofgroup-14 elements: C >Si> Ge> Sn< Pb

Pick the correct order on decreasin trend of atomic size

Halides of Si, Ge and Sn form complexes, while carbon halides do not form complexes, because

The catenation tendency of C, Si , and Ge is in the order Ge lt Si lt C . The bond energies (in kJ mol^(-1) ) of C-C-, Si-Si , and Ge-Ge bonds, respectively, are
