    Commercially, methanol is manufactured by which of the following method?

    A)  Catalytic reduction of CO in the presence of \[ZnO,C{{r}_{2}}{{O}_{3}}\]

    B)  The reaction of\[C{{H}_{4}}\]with water vapour in the presence of Ni catalyst at\[900{}^\circ C\]

    C)  By the reaction of formaldehyde with\[LiAl{{H}_{4}}\]

    D)  By the reaction of\[HCHO\]with aqueous\[KOH\]

    Correct Answer: A

    Solution :

     Commercially, methanol is manufactured by the catalytic reduction of CO in the presence of\[ZnO,C{{r}_{2}}{{O}_{3}}\]. \[\underbrace{CO+{{H}_{2}}}_{water\text{ }gas}+{{H}_{2}}\xrightarrow[{}]{C{{r}_{2}}{{O}_{3}}-ZnO}\underset{methanol}{\mathop{C{{H}_{3}}OH}}\,\]
