Answer:
Butan-2-one
Explanation:
1. 1700 cm⁻¹
A strong peak near 1700 cm⁻¹ is almost certainly a carbonyl (C=O) group.
2. Triplet-quartet
A triplet-quartet pattern indicates an ethyl group.
The 2H quartet is a CH₂ adjacent to a CH₃. The peak normally occurs at δ 1.3, but it is shifted 1.2 ppm downfield to δ 2.47 by an adjacent C=O group.
The 3H triplet at δ 1.05 is the methyl group. It, too, is shifted downfield from its normal position at δ 0.9. The effect is smaller, because the methyl group is further from the carbonyl.
3. 3H(s) at δ 2.13
This indicates a CH₃ group with no adjacent hydrogen atoms.
It is shifted 0.8 ppm downfield to δ 2.13 by the adjacent C=O group.
4. Identification
The identified pieces are CH₃CH₂-, -(CO)-, and -CH₃. There is only one way to put them together: CH₃CH₂-(C=O)-CH₃.
The compound is butan-2-one.
Answer : The value of equilibrium constant (Kc) is, 0.0154
Explanation :
The given chemical reaction is:
![SO_2Cl_2(g)\rightarrow SO_2(g)+Cl_2(g)](https://tex.z-dn.net/?f=SO_2Cl_2%28g%29%5Crightarrow%20SO_2%28g%29%2BCl_2%28g%29)

As we are given:
Concentration of
at equilibrium = ![1.3\times 10^{-2}M](https://tex.z-dn.net/?f=1.3%5Ctimes%2010%5E%7B-2%7DM)
That means,
![x=1.3\times 10^{-2}M](https://tex.z-dn.net/?f=x%3D1.3%5Ctimes%2010%5E%7B-2%7DM)
The expression for equilibrium constant is:
![K_c=\frac{[SO_2][Cl_2]}{[SO_2Cl_2]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BSO_2%5D%5BCl_2%5D%7D%7B%5BSO_2Cl_2%5D%7D)
Now put all the given values in this expression, we get:
![K_c=\frac{(x)\times (x)}{2.4\times 10^{-2}-x}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%28x%29%5Ctimes%20%28x%29%7D%7B2.4%5Ctimes%2010%5E%7B-2%7D-x%7D)
![K_c=\frac{(1.3\times 10^{-2})\times (1.3\times 10^{-2})}{2.4\times 10^{-2}-1.3\times 10^{-2}}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%281.3%5Ctimes%2010%5E%7B-2%7D%29%5Ctimes%20%281.3%5Ctimes%2010%5E%7B-2%7D%29%7D%7B2.4%5Ctimes%2010%5E%7B-2%7D-1.3%5Ctimes%2010%5E%7B-2%7D%7D)
![K_c=0.0154](https://tex.z-dn.net/?f=K_c%3D0.0154)
Thus, the value of equilibrium constant (Kc) is, 0.0154
It would be 1A bc then the +1 charge will cancel out chlorine’s -1 charge
