Question
The correct increasing order of $C - H(A)$, $C - O(B),C = O(C)$ and $C \equiv N(D)$ bonds in terms of covalent bond length is:
Options
A.$, $C - O
B.,C = O
C.$ and $C \equiv N
D.
64. The correct increasing order of $C - H$, $C - O(B),C = O(C)$ and $C \equiv N(D)$ bonds in terms of covalent bond length is:
(1) A $<$ B $<$ C $<$ D
(2) A $<$ D $<$ C $<$ B
(3) D $<$ C $<$ B $<$ A
(4) D $<$ C $<$ A $<$ B
Solution
$\ C - H(A)\ 107pm$
$$C \equiv N(D)\ 116pm $$C-O(B) 143 pm
$$C = O(C)\ 121pm$$
2-Chlorobutane is optically active and chiral molecule
Molecular formula $\Rightarrow C_{4}H_{9}Cl$
Molar mass $= 48 + 9 + 35.5 = 92.5$
$$\% OC = \frac{48}{92.5} \times 100 = 51.89\%$$
