1.Select the correct statement about elements of group 15th.a.The order of stability of oxidation state for +3+3+3 is Bi3+>Sb3+>As3+Bi^{3+} > Sb^{3+} > As^{3+}Bi3+>Sb3+>As3+ and for +5+5+5 is Bi5+<Sb5+<As5+Bi^{5+} < Sb^{5+} < As^{5+}Bi5+<Sb5+<As5+b.In the case of nitrogen, all oxidation states from +1+1+1 to +4+4+4 tend to disproportionate in acid solution.c.There is considerable increase in covalent radius from NNN to PPP but from AsAsAs to BiBiBi only a small increase in covalent radius is observed.d.All of theseLogin to continueOnly logged in users canattempt or see the solution.
