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’.

- What are aromatic hydrocarbons? Benzene exhibits resonance. Explain. What are the bond angles in benzene? Give a detailed description of the bonding in benzene. The electrons in benzene are delocalized, while the electrons in simple alkenes and alkynes are localized. Explain the difference.arrow_forwardComplete and balance the following combustion reactions. Assume that each hydrocarbon is converted completely to carbon dioxide and water.

- Describe a simple CHEMICAL test to distinguish between: Methanoic acid (HCO2H) and Ethanoic acid (CH3CO2H) Dimethyl ether (CH3OCH3) and Ethanol (CH3CH2OH)arrow_forwardOrganic compounds may have characteristic odors as well as other characteristic physical properties. For example, the distinct odor of the seashore at low tide results in part from the presence of dimethyl sulfide (CH3SCH3), a molecule with a similar structure to dimethyl ether (CH3OCH3). Ethanethiol (CH3CH2SH), also called mercaptan, is an isomer of dimethyl sulfide with a much less pleasant odor.The table lists four related compounds and their enthalpies of vaporization (ΔH°vap) in kJ/mol. Compound ΔH°vap (kJ/mol) CH3OCH3 23 CH3SCH3 28 CH3CH2SH 27.5 CH3CH2OH 42 Rank the following compounds in order of increasing strength of their intermolecular forces, given the ΔH°vap listed for each. Place the compound with the strongest intermolecular forces (IMFs) at the top of the list. (Strongest to weaknest). Why is ΔHºvap for CH3SCH3 greater than ΔHºvap for CH3OCH3? A. CH3OCH3 is more polar. B. CH3SCH3 has stronger dipole–dipole attractions. C. CH3OCH3 can form…arrow_forwardCompounds X and Y both have the formula C7H14.
