How can we differ between ethene and ethene by tollen's reagent?
Answers
Ethene:
Ethene is a hydrocarbon composed of two carbon atoms and four hydrogen atoms.
Common name used for ethene is ethylene.
The carbon atoms are sp² hybridized in ethene.
Molecular formula for ethene is C2H4.
The distance between two carbon atoms in ethene is about 133.9 pm.
The distance between carbon (C) and hydrogen (H) atoms in ethene is 108.7 pm.
The molecular geometry of ethene is planer.
There is one pi bond in ethene.
The molar mass of ethene is about 28 g/mol.
The melting point of ethene is -169.4°C.
The bond angle in ethene is 121.3°.
The two carbon atoms are bonded to each other through a double bond and the hydrogen atoms are bonded to these carbon atoms through single bonds.
The natural sources of ethene include natural gases and petroleum oil.
At STP, ethene is a colourless gas.
Ethene is used in polymerization process as a monomer to produce polyethylene.
Ethene is also used to produce ethylene oxide in order to produce detergents and surfactants like chemicals
Ethyne
Ethyne is a hydrocarbon composed of two carbon atoms and two hydrogen atoms.
The common name used for ethyne is acetylene.
The carbon atoms are sp hybridized in ethyne.
The molecular formula is given as C2H2.
The distance between two carbon atoms in ethyne is about 120.3 pm.
The distance between carbon (C) and hydrogen (H) in ethyne is about 106.0pm.
The molecular geometry of ethyne is linear.
There are two pi binds in ethyne.
The molar mass of ethyne is about 26.04 g/mol.
The melting point of ethyne is -80.8°C.
The bond angle in ethyne is 180°.
The two carbon atoms are bonded with each other in ethyne through tripple bond and the hydrogen atoms are bonded to these carbon atoms through single bond.
The natural sources of ethyne include natural gas.
Ethyne is also a colourless gas which is lighter than air.
Approximately 80% of ethyne /acetylene produced annully is used in chemical synthesis and 20% is used primarily for oxyacetylene gas welding and cutting due to the high temperature of the flame .
Acetylene is also used in carbide lamps, on vintage cars and still sometimes used by cavers.
hope it helps
it is perfect answer
