Sigma Bond



Pi - Bond



1)      A sigma bond is formed by the end to end overlap of half – filled atomic orbitals along the inter – nuclear axis. The overlapping involves two s – orbitals, one s and p – orbital or two p - orbitals



A pi – bond is formed by the sidewise overlap of two half – filled p - orbitals



2)      In this case, the overlapping can take place to a larger extent and therefore, the bond formed is a strong bond



In the formation of Pi - bond the overlapping occurs to a lesser extent and therefore, the bond is weak.



3)      The molecular orbital is symmetrical about the intermolecular axis.



The molecular orbitals is discontinuous and consists of two charged clouds above and below the plane of atoms.



4)      There can be free rotation of atoms around o- - bond



Because of overlapping of the electrons clouds above and below the plane of the atoms, free rotation of atoms around Pi - bond is not possible.



5)      The bond may be present between two atoms either alone or along with Pi- bond.



The bound is always present between two atoms in addition to sigma bond.



6)      In the formation of sigma bond, s – orbitals can participate.



s – orbitals cannot participate in the formation of pi - bond

For the reaction CO2 (g) + H2(g) ↔ CO(g) + H2O(g) the value of K at 552°C is 0.137. If 3.0 moles of CO2, 3.0 moles of H2 , 1.5 mole of CO and 1.5 mole of H2O are initially present in a 1.0 L...
 
 
Here K p = K c . Taking dissociation constant as a, ((3a) 2 /(3(1-a)) 2 )=0.137 Solving for a, =0.27. Hence equillibrium concentrations of CO and H 2 O are 1.5+.81=2.31moles/L each and that...

Methanol is more acidic than water pK a of methanol = 15.54 pK a of water = 15.74 you know lesser pKa means more acidic , methanol is more acidic than water ;

water is more acidic because in water molecule there is no alkyl group . alkyl group is electron donating group which decreases the acidity of methanol
