Hybridization is the process of mixing and aligning orbitals in form and energy, in which the redistribution of electronic densities is close to the energy of orbitals, and as a result they become equivalent. In the acetylene molecule is observed the sp mode of hybridization. sp-hybridization is a hybridization involving the atomic orbitals of one s and one p-electron. When a combination of one s- and one p-orbitals arises, there are two sp-hybridized orbitals. These two sp-hybridized orbitals placed symmetrically at a valence angle of 180°. Links formed with the participation of electrons of valence orbitals are also placed at an angle of 180° , which determines the linear form of the molecule. Examples of chemical compounds characterized by sp-hybridization: BeCl2, BeH2, CO, CO2, HCN, acetylene hydrocarbons and other organic compounds.

3. (a) Write a balanced chemical equation for the incomplete combustion of acetylene gas. (b) Write a balanced chemical equation for the complete combustion of acetylene gas.

In the incomplete combustion of acetylene with oxygen, water and carbon monoxide are formed, rather than carbon dioxide which is formed in the complete combustion. So the balanced equation for...

how will you synthesis: 1)Acetylene from ethylene 2)1-Butyne from Acetylene

1) H2C=CH2 + Br2 --gt; Br-HC=CH-Br Br-HC=CH-Br + KOH (in alcohol) --gt; HC=CH 2) HC=CH+ Na ---gt; HC=CNa HC=CNa+ CH3Cl --gt; HC=C-CH3

acetylene burn in air forming carbon di-oxide and water vapour calculate the volume of air required to completely burn 50 cm cube

C2H2 + 5/2O2 ----------------gt; 2CO2 + H2O Burning of 1 mole of C2H2 requires 2.5 mole O2 That means 2.5 x 50 cm3 = 125 cm3 O2 Let total air...

Identify the type of hybridization of the carbon atoms in the following compound: CH 2 = CHCOCH 3 Also predict the carbon-carbon and carbon-hydrogen bond length using Table 4.4.

The carbons of CH2=CH and CO have sp2-hybridization. The carbons of CH3 have sp3-hybridization. The distances of C(sp3)-C(sp3) bonds are around of 154 pm. The distances of C(sp3)-C(sp2) bonds are...
