• # question_answer Propane cannot be prepared from which reaction [DCE 2003] A) $C{{H}_{3}}-CH=C{{H}_{2}}\underset{O{{H}^{-}}}{\mathop{\xrightarrow{{{B}_{2}}{{H}_{6}}}}}\,$ B) $C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}I\underset{P}{\mathop{\xrightarrow{HI}}}\,$ C) $C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}Cl\xrightarrow{Na}$ D) None of these

Hydroboration of alkenes followed by hydrolysis in basic medium yield alcohols and not the alkanes. $R-CH=C{{H}_{2}}\xrightarrow{{{B}_{2}}{{H}_{6}}}{{(R-C{{H}_{2}}-C{{H}_{2}})}_{3}}-B$$\xrightarrow{O{{H}^{-}}}R-C{{H}_{2}}-C{{H}_{2}}OH$
