1.	Define the following terms with example.A. Wurtz Reaction. B. Chain Isomerism. C. Dihedral Angle.
Answer» (a) Wurtz Reaction: When alkyl halides react with sodium metal in the presence of dry ether the product obtained is alkanes with more no. of carbon atoms. E.g. CH₃ – Cl + 2Na +Cl – CH3 --------> 2NaCl + CH₃ – CH₃ (b) Chain Isomerism: The isomers which differ with respect to the nature of the carbon atom which may be either straight chain or branched chain. E.g. For C₄H₁₀ butane the two isomers obtained are CH₃CH₂CH₂CH₃ (c) Dihedral Angle:- The angle between the two non bonded hydrogen atoms of the two neighbouring carbon atoms in ethane is called Dihedral Angle.
