Answer:Carbon compounds are compounds having carbon as an essential element. These have generally covalent bonding.
There are many types of carbon compounds on the basis of the other elements, but the most important of them are hydrocarbons. They are compounds only made up of carbon and hydrogen. Examples can be-
Ethanol (CH3CH2OH)
Acetone [(CH3)2CO]
Butanone [ CH3C(O)CH2CH3]

Answer:
The freezing point is -3.72 degrees Celsius
Explanation:
In this question, by assuming the complete dissociation of the salt, we want to calculate the freezing point of an aqueous 1 M NaCl solution .
We proceed as follows;
Firstly, we write the dissociation equation;
NaCl ——> Na+ + Cl-
So the number of ions present in the dissociation is 2. This means that the Vant Hogg factor also called I = 2
Mathematically;
ΔTf = Kf*m*i
m represents the molality which is given as 1
So by substituting the values, we have;
ΔTf = 1.86 * 1 * 2 = 3.72 degrees Celcius
The freezing point however is 0 - ΔTf = 0 - 3.72 = -3.72 degrees Celcius
