NEET Chemistry The p-Block Elements (XII) Questions Solved


The incorrect statement regarding 15th group hydrides (EH3)E=N, P, As, Sb, Bi

(a) NH3>PH3>AsH3>SbH3>BiH3 : Thermal stability

(b) N-H>P-H>As-H>Sb-H>Bi-H : E-H bond dissociation enthalpy

(c) NH3>PH3>AsH3>SbH3>BiH3 : Reducing character

(d) NH3>PH3>AsH3>SbH3>BiH3 : Basicity

(c)  Reducing character 1'EH' bond dissociation enthalpy

       Hence, correct reducing character is NH3<PH3<AsH3<SbH3<BiH3 .
