HOTS
The various types of hydrides and examples of each type are given below :
Hydride type Compound
A Electron deficient i LiH
B Saline ii $C{H}_4$
C Electron-precise iii $N{H}_3$
D Interstitial iv $B_2{H}_6$
E Electron rich v CrH
Choose the correct matching from the code 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) - i(v), (D) - (ii), (E) - (i)

Answer 1

The correct option is B (A)- (iv), (B) - (i), (C) - (ii), (D) - (v), (E) - (iii)

(A) electron deficient $\to B_2{H}_6$

(which can accept a love pair of electron)

(B) saline (Ionic hydrides)$\to LiH$

(C) Electron precise $\to C{H}_4$

(which can neither accept nor give pair of $e^{-}{14}^{th}$ group element makes this hydride)

(D) Interstitial $\to CrH$

(d block element from intersfical hydride)

(E) Electron rich $\to N{H}_3$

molecule which can donate pair of electron

(A)-iv, (B)-(i), (C)-(ii), (D)-(v), (E)-(iii)
