The compound that is used as an anesthetic is?
CCl4
CH Cl3
CH2Cl2
CH3Cl
Correct answer is B
- Chloroform / tricholoromethane ( CHCl\(_3\) ) is a potent anaesthetic agent.
- Though Chloroform is no longer used as an anaesthetic for several reasons, the most important of which is the relatively high risk of complications, including possible heart failure
Benzene
Alkynes
Alkenes
Alkanes
Correct answer is D
Bromine water is an orange solution of bromine. It becomes colorless when it is shaken with an alkene. Alkenes can decolorize bromine water, but alkanes cannot.
X is ethene which decolorizes bromine water showing that ethene is unsaturated.
Y is an alkane.
The haloalkanes used in dry-cleaning industries are?
trichloromethane and tetrachloromethane
chloroethene and dichloroethene
trichloroethene and tetrachloroethene
chloroethane and dichloroethene
Correct answer is A
- Both trichloromethane and tetrachloromethane are such important organic solvent.
One of the major uses of alkane is?
as domestic and industrial fuel
in the hydrogenation of oils
in the textile industries
in the production of plastics
Correct answer is A
- Alkanes will react with Oxygen if they are given sufficient Activation Energy. This will result in a highly Exothermic reaction, producing Carbon Dioxide and Water, which makes Alkanes very useful as fuels.
C3H7OH → C4H10 → C7H10
C4H10 → C7H16 → C3H7OH
C7H16 → C3H7OH → C4H10
C4H10 → C3H7OH → C7H16
Correct answer is D
C3H7OH ( PROPANOL) ⇒ 97ºC
C7H16 ( HEPTANE ) ⇒ 98.42ºC ;and
C4H10 ( BUTANE ) ⇒ -1ºC
