Arrange the hydrides of group - 15 elements in the increasing order of basic strength and decreasing order of basic strength and decreasing order of reducing character.

Text Solution

Verified by Experts

i. Increasing order of basic strength of Group - 15 elements hydrides is
`"BiH"_(3) lt"SbH"_(3)lt"AsH"_(3)lt"PH"_(3)lt"NH"_(3)`.
ii. Decreasing order of reducing character of Group - 15 elements hydrides is
`"BiH"_(3)gt"SbH"_(3)gt"AsH"_(3)gt"PH"_(3)gt"NH"_(3)`.
