Here are the questions of chp 1...... I will upload other chapters soon... All the best chemist.... please discuss your queries here so I could get advantage.....this is especially for you asma mehvish.

Give example in each case and explain the phenomenon of sp3, sp2 and sp hybridization.(2001)

Explain the significance of pi bond. (2002)

(a) In what respect sigma and pi bond are different from each other.
(b)What are H-bonds and how they affect the properties of organic compounds.
(c)Write an essay on hybridization and its significance in predicting the shapes of molecules (2007)

(a) what is mesmerism? Give the conditions necessary for mesmerism.
(b)what is intermolecular and intermolecular hydrogen bonding? Illustrate with example.
(c)Indicate the type of hybridization in the following:
Formaldehyde ,hydrogen cyanide ,dimethyl ether ,acetylene. (2010)

Differentiate between intermolecular and intramolecular hydrogen bonding. Discuss effects of hydrogen bonding and any two properties of organic compounds. Support your answer with suitable example. (2011)

(a) Explain why dipole moment if BF3 is zero ?
(b) Why dipole moment of NH3 is greater than NF3?
(c) Why does So2 have dipole moment while CO2 doesn't ? (2012)

(a) Why do we use three p- orbitals(2px,2py,2pz) alone to form three equivalent hybrid orbitals of carbon?
(b)Give an example of element that undergoes sp hybridization in forming covalent bond with other elements.what is the value of angle between the bond that results from s-sp overlap of atomic orbitals. (2013)

Give one example with structure of each of the following:
s-sp hybridization , sp2-sp2 hybridization , sp- sp2 hybridization. (2014)
