Q. The following are some statements related to VA group hydrides I. Reducing property Increases from NH_{3} to BiH_{3} II. Tendency to donate lone pair decreases from NH_{3} to BiH_{3} III. Thermal stability of hydrides decreases from NH_{3} to BiH_{3} IV. Bond angle of hydrides decreases from NH_{3}to BiH_{3} The correct statements are
A) I, II, III and IV
B) I, III and IV
C) I, II, IV
D) I and IV
Explanation
(a)
The reducing property of the hydrides of VA group increases from NH_{3} to BiH_{3}
NH_{3}<PH_{3}<AsH_{3}<SbH_{3}<BiH_{3}
The tendency to donate lone pair or basic strength decreases from NH_{3} to BiH_{3}
NH_{3}>PH_{3}>AsH_{3}>SbH_{3}>BiH_{3}
Thermal stability of VA group hydrides deceases from NH_{3} to BiH_{3}
NH_{3}>PH_{3}>AsH_{3}>SbH_{3}>BiH_{3}
Bond angle of VA group hydrides decreases from NH_{3} to BiH_{3}.
NH_{3}>PH_{3}>AsH_{3}>SbH_{3}>BiH_{3}
