c2h2
CH2 is the empirical formula for C4H8 because it is an alkene and the empirical fomula for ALL alkenes are C(n)H(2n) n being the number of molecules!!! (^-^)
C2H4 (ethylene) contains a sp2-sp2 sigma bond. In ethylene, each carbon atom is sp2 hybridized, forming a sigma bond between them.
Molecules that permit free rotation about the carbon-carbon bond include C2H2 (acetylene) and C2H4 (ethylene) due to the presence of a triple bond and a double bond respectively. On the other hand, C2Cl4 (tetrachloroethylene) and C2H5Cl (chloroethane) do not permit free rotation about the carbon-carbon bond due to the presence of chlorine atoms or a bulky ethyl group that restrict rotation.
There are many compounds containing Carbon and Hydrogen: * Methane (CH4) * Ethane (C2H6) * Propane (C3H8) * Ethylene (C2H4) * Acetylene (C2H2)
There is one double bond in C2H4, which is between the two carbon atoms in the molecule.
The smallest alkyne is ethyne (C2H2). You're welcome!

The standard free energy of formation of C2H2 is +209.20 kJ/mole, while that of C2H4 is +68.15 kJ/mole (and H2 zero since it is an element in its standard state). thus, at standard temperature and pressure (25 C, 1 Bar pressure) the reaction C2H2 + H2 -> C2H4 has a standard free energy change of -141 kJ/mole and thus "spontaneous" in that equilibrium constant >> 1.

No, methane is actually the simplest saturated hydrocarbon as it consists of single carbon and four hydrogen atoms. Unsaturated hydrocarbons contain at least one carbon-carbon double or triple bond, such as ethylene (C2H4) or acetylene (C2H2).

One Mole of C2H4 will containt 6.0221415×10^23 molecules of C2H4. Therefore 2.23 Moles of C2H4 will contain 1.39713683x10^24 molecules of C2H4. There are 4 Hydrogen atoms in C2H4, so 1.39713683x10^24 x 4 = 5.58854732X10^25 atoms of hydrogen.
There are two double bonds in a carbon dioxide molecule.
C2H2 (acetylene) is a linear molecule.
