Question

The various types of hydrides and examples of each type are given below : 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)

Answer 1

Answer: (B)

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

Answer 2

(A) Electron deficient $\rightarrow B _{2} H _{6}$
$(\because$ It has $3 c -2 e$ structure, which shows that B-atom has electron deficient centre).

(B) Saline $\rightarrow$ LiH is called saline.

(C) Electron precise $\rightarrow CH _{4}$
$(\because$ It has perfect complete octet for $C$ -atom $)$.

(D) Interstitial $\rightarrow CrH$ Here, hydrogen atoms are trapped in the interstitial sites of crystal of Cr.

(E) Electron rich $\rightarrow \overset{\bullet \bullet}{N} H_{3},$ because nitrogen has lone pair of electrons in its outermost shell.

Hence, correct order is (A)- (iv), (B)- (i), (c)- (ii),(D)- (v), (E)- (iii)
