Draw the structure of a compound with the molecular formula C9H10O2 that exhibits the following spectral data. (a) IR: 3005 cm-1

Nikitich [7]

Answer:

The answer is 3-Phenylpropanoic acid (see attached structure)

Explanation:

From spectral data:

3005 cm-1 ⇒ carboxylic acid (broad band)

1670 cm-1 ⇒ C=C

1603 cm-1 ⇒ Aromatic C-C bond

H NMR frequency at 2.6 ppm, singlet, ⇒ OH with no surrounding protons, possible deshielding (clearer investigation of spectrum would be expedient).

Hence, our C9H10O2 compound has an aromatic ring and carboxylic acid group attached to it.

At particular temperature, Kp = 70.9 for the following reactionN2O4(g) == 2NO2(g)1. A certain pressure of N2O4 is initially adde

elixir [45]

Answer : The partial pressure of $NO_2$ is, 12.34 atm

Explanation :

For the given chemical reaction:

$N_2O_4(g)\rightleftharpoons 2NO_2(g)$

The expression of $K_p$ for above reaction follows:

$K_p=\frac{(P_{NO_2})^2}{P_{N_2O_4}}$ ........(1)

The equilibrium reaction is:

$N_2O_4(g)\rightleftharpoons 2NO_2(g)$

Initial x 0

At eqm (x-y) 2y

Putting values in expression 1, we get:

$70.9=\frac{(2y)^2}{(x-y)}$ ..............(2)

As we are given that, 25.8 % of $N_2O_4$ remains at equilibrium. That means,

$25.8\% \times x=(x-y)$

$\frac{25.8}{100}\times x=(x-y)$

$0.258\times x=(x-y)$

$0.742x=y$ ..............(3)

Now put equation 3 in 2, we get the value of 'x'.

$70.9=\frac{(2\times 0.742x)^2}{(x-0.742x)}$

$x=8.31$

Now put the value of 'x' in equation 3, we get:

$0.742x=y$

$0.742\times 8.31=y$

$y=6.17$

Now we have to calculate the new partial pressure of $NO_2$ at equilibrium.

Partial pressure of $NO_2$ = (2y) = (2\times 6.17) = 12.34 atm

Hence, the partial pressure of $NO_2$ is, 12.34 atm
