Concept explainers
(a)
Interpretation:
Interpret the following statement is true or false.
‘Freons are member of chlorofluorocarbons’.
Concept Introduction:
Refrigerator releases Chlorofluorocarbon which can also be emitted from air conditioner as well. It contains chlorine and fluorine attached on carbon and also known as Freons. Freons are nontoxic in nature and released from cooling machines. Freons are non flammable and odorless which is used as propellant in air sprays.
(b)
Interpretation:
Interpret the following statement is true or false.
‘Freons used as propellent in sprays to be identified’.

(c)
Interpretation:
Interpret the following statement is true or false.
‘Freons causes destruction of ozone to be identified’.
Concept Introduction:
Exothermic reaction is the reaction for the liberation of energy in a reaction while endothermic reaction takes place with the consumption of energy. Usually the combustion of
Endothermic reaction having +ve dH value while exothermic reaction having −ve dH value.
(d)
Interpretation:
Interpret the following statement is true or false.
‘Name of CH2 Cl2 is dichloromethane, methyl chloride, chloroform to be identified’.

- 11-62(Chemical Connections 11C) What are Freons? Why were they considered ideal compounds to use as heat-transfer agents in refrigeration systems? Give structural formulas of two Freons used for this purpose.arrow_forwardAs stated in Section 11-9, the wax found in apple skins is an unbranched alkane with the molecular formula C^H^. Explain how the presence of this alkane in apple skins prevents the loss of moisture from within the apple.arrow_forwardIs the reaction between an alkene and a halogen a substitution reaction(displacement reaction) or another reaction? Explain the reaction mechanism by giving an example.arrow_forward
- What hydrocarbon with molecular formula C4H10 forms only two monochlorinated products? Both products are achiral.arrow_forwardEthanol, C2H6O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The heat of combustion of ethanol is 326.7 kcal/mol.The heat of combustion of 2-methylhexane, C7H16, is 1.150×103 kcal/mol. How much energy is released during the complete combustion of 446 grams of 2-methylhexane ??? kcalAssuming the same efficiency, would 446 grams of ethanol provide more, less, or the same amount of energy as 446 grams of 2-methylhexane?arrow_forwardEthanol, C2H6O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol.
