A compound with molecular formula C4H8O2, shows absorptions at 2500-3300 cm-1 (broad), 1720 cm-1 and at 1200 cm-1 on the IR spec

Answer:

Butanoic Acid:

I have attached the structure of Butanoic Acid. Please refer to the attachment.

Explanation:

Solution:

First of all, we need to calculate the double bond equivalent (DBE) for the compound given:

Compound = C4H8O2

DBE = (C +1) - (H + X - N)/2

C = no. of carbons

H = no. of Hydrogen

X = no. of Halogens

N = no. of Nitrogen

DBE = (4+1) - (8/2)

DBE = 5-4

DBE = 1

It indicates the presence of 1 double bond in the possible structure.

Further structure can be identified by looking the peak values of the spectrum. So, we have,

2500 - 3300 = it indicates the presence of -COOH group

1720 = it indicates the (C=0) stretching  

1200 = It indicates the (C-O) stretching

SO, the possible structure is

Butanoic Acid:

I have attached the structure of Butanoic Acid. Please refer to the attachment.

A 7.0 L sample of gas begins at 2.5 atm and 320. K. What is the new pressure if the temperature is changed to 273 K and the volu
enyata [817]

Answer:

2.1 atm

Explanation:

We are given the following variables to work with:

Initial pressure (P1): 2.5 atm

Initial temperature (T1): 320 K

Final temperature (T2): 273 K

Constant volume: 7.0 L

We are asked to find the final pressure (P2). Since volume is constant, we want to choose a gas law equation that relates initial pressure and temperature to final pressure and temperature. Gay-Lussac's law does this:

\frac{P_{1}}{T_1} =\frac{P_{2}}{T_2} \\

We can rearrange the law algebraically to solve for P_{2}.

{P_{2}} =\frac{(T_2)(P_{1} )}{T_1} \\

Substitute your known variables and solve:

P_2 = \frac{273K(2.5atm)}{320K}  = 2.1 atm
