A chloro compound "A".
(i) forms aldehydes on ozonolysis followed by the hydrolysis.
(ii) when vaporized completely 1.53 g of A, gives 448 mL of vapour at STP.
The number of carbon atoms in a molecule of compound A is ___________.
(i) forms aldehydes on ozonolysis followed by the hydrolysis.
(ii) when vaporized completely 1.53 g of A, gives 448 mL of vapour at STP.
The number of carbon atoms in a molecule of compound A is ___________.
Correct Answer: 3
Explanation:
448 ml of A $\Rightarrow$ 1.53 gm A
22400 ml of A $\Rightarrow$ ${{1.53} \over {448}}$ $\times$ 22400 gm A = 76.5 Agm
$\mathop {{H_3}CHC - CH - Cl}\limits_{It\,has\,3\,carbon\,atoms} \mathrel{\mathop{\kern0pt\longrightarrow} \limits_{Zn/{H_2}O}^{{O_3}}} \mathop {C{H_3} - CH = O}\limits_{Aldehyde} $
& MM is 36 + 5 + 35.5 = 76.5
22400 ml of A $\Rightarrow$ ${{1.53} \over {448}}$ $\times$ 22400 gm A = 76.5 Agm
$\mathop {{H_3}CHC - CH - Cl}\limits_{It\,has\,3\,carbon\,atoms} \mathrel{\mathop{\kern0pt\longrightarrow} \limits_{Zn/{H_2}O}^{{O_3}}} \mathop {C{H_3} - CH = O}\limits_{Aldehyde} $
