Question

Match the compounds given in column I with oxidation states of carbon given in column II and mark the appropriate choice.

	Column I		Column II
(A)	$C_{6}H_{12}O_{6}$	(i)	+3
(B)	$CHCl_{3}$	(ii)	-3
(C)	$CH_{3}CH_{3}$	(iii)	+2
(D)	$(COOH)_{2}$	(iv)	0

• A. (A) $\rightarrow$ (iv), (B) $\rightarrow$ (iii), (C) $\rightarrow$ (ii), (D) $\rightarrow$ (i)
• B. (A) $\rightarrow$ (i), (B) $\rightarrow$ (ii), (C) $\rightarrow$ (iii), (D) $\rightarrow$ (iv)
• C. (A) $\rightarrow$ (ii),(B) $\rightarrow$ (iii),(C) $\rightarrow$ (iv), (D) $\rightarrow$ (i)
• D. (A) $\rightarrow$ (iii), (B) $\rightarrow$ (ii), (C) $\rightarrow$ (i), (D) $\rightarrow$ (iv)

Answer 1

Answer: (A)

(A) $\rightarrow$ (iv), (B) $\rightarrow$ (iii), (C) $\rightarrow$ (ii), (D) $\rightarrow$ (i)

Answer 2

: $C_{6}H_{12}O_{6}:6x + 12 + ( - 12) = 0 \Rightarrow x = 0$

$CHCl_{3}:x + 1 + ( - 3) = 0 \Rightarrow x = + 2$

$CH_{3}CH_{3};x + 3 + x + 3 = 0 \Rightarrow x = - 3$

$(COOH)_{2}:x + x + ( - 4 \times 2) + ( + 2) = 0 \Rightarrow x = + 3$
