Which of the following statements is not correct? (A) The first ionization energies in (kJ mol- 1 ) of carbon, silicon, germanium, tin and lead are 1086, 786, 761, 708 and 715 respectively (B) Down the group, ionization energy decreases regularly from B to T1 in boron family (C) Among oxides of the elements of carbon family, CO is neutral, GeO is acidic and SnO is amphoteric (D) The 4f and 5f-inner transition elements are placed separately at the bottom of the periodic table

Tardigrade Admin · Accepted Answer

In boron family ionization energy decreases abnormally down the group and the order is as follows B > Tl > Ga > Al > In

Q. Which of the following statements is not correct?

The first ionization energies in (kJ $m o l^{- 1}$ ) of carbon, silicon, germanium, tin and lead are 1086, 786, 761, 708 and 715 respectively

Down the group, ionization energy decreases regularly from B to T1 in boron family

Among oxides of the elements of carbon family, CO is neutral, GeO is acidic and SnO is amphoteric

The 4f and 5f-inner transition elements are placed separately at the bottom of the periodic table

In boron family ionization energy decreases abnormally down the group and the order is as follows

B > Tl > Ga > Al > In
