Question

The various types of hydrides and examples of each type are given below. {ll} Hydride type & Compound
(a) Electron deficient & (i) LiH
(b) Saline & (ii) CH$_4$
(c) Electron-precise & (iii) NH$_3$
(d) Interstitial & (iv) B$_2$H$_6$
(e) Electron rich & (v) CrH
Choose the correct matching from the codes given below

• A. (a)-(ii), (b)-(iv), (c)-(v), (d)-(iii), (e)-(i)
• B. (a)-(iv), (b)-(i), (c)-(ii), (d)-(v), (e)-(iii)
• C. (a)-(iv), (b)-(iii), (c)-(v), (d)-(ii), (e)-(i)
• D. (a)-(v), (b)-(iii), (c)-(iv), (d)-(ii), (e)-(i)
• E. (a)-(iv), (b)-(v), (c)-(i), (d)-(ii), (e)-(iii)

Hint:

Quick memory trick:
• Boron → Electron deficient
• Alkali metals → Saline
• Carbon compounds → Electron precise
• Transition metals → Interstitial
• Nitrogen → Electron rich (lone pair)

Answer 1
