Question

An alkane $C_6{H}_{14}\left(X\right)$ can be obtained by the reduction of five different alkyl halides $C_6{H}_{13}Cl$ (only structural isomers) with $Zn-dil.HCl.$ The IUPAC name of X satisfying above condition is

• A. 2,3-dimethylbutane
• B. Hexane
• C. 2-methylpentane
• D. 2,2-dimethyl butane

Answer 1

The correct option is C 2-methylpentane

2-methyl pentane has five types of hydrogen, therefore, it can be obtained by reduction of five different halides as:


All of the above chloroalkanes, reduction with $Zn-dil.HCl$ would give the same 2-methyl pentane.
