Consider the reaction, ${\left({\mathrm{CH}}_3\right)}_2\mathrm{CHOH} \stackrel{{\mathrm{CH}}_3\mathrm{MgI}}{\to }\mathrm{X}.$The compound ‘X’ in the reaction is

Active hydrogen compounds react with Grignard's reagent to give Alkanes. The reaction is called Zerwitnoff's reaction;

${\mathrm{CH}}_3\mathrm{MgI}+{\left({\mathrm{CH}}_3\right)}_2\mathrm{CHOH}\to {\mathrm{CH}}_4+\mathrm{Mg}\left(\mathrm{I}\right)\mathrm{OCH}{\left({\mathrm{CH}}_3\right)}_2;$
