In the following sequence of reactions,

$CH subscript 3 CH subscript 2 OH space rightwards arrow with space space space straight P space plus space straight I subscript 2 on top straight A space rightwards arrow from ether to Mg of straight B space rightwards arrow with HCHO on top space straight C space rightwards arrow with straight H subscript 2 straight O on top space straight D comma space then$ compound ‘D’ is

butanal

n-butyl alcohol

n-propyl alcohol

propanal

Solution

n-propyl alcohol

CH subscript 3 CH subscript 2 OH space rightwards arrow with straight P space plus space straight I subscript 2 on top space stack CH subscript 3 CH subscript 2 straight I with left parenthesis straight A right parenthesis below space rightwards arrow from dry space ether to Mg of space stack CH subscript 3 CH subscript 2 MgI with left parenthesis straight B right parenthesis below rightwards arrow with HCHO on top space stack CH subscript 3 CH subscript 2 CH subscript 2 OMgI with left parenthesis straight C right parenthesis below space rightwards arrow with straight H subscript 2 straight O on top stack space CH subscript 3 CH subscript 2 CH subscript 2 OH with left parenthesis straight D right parenthesis below space plus space Mg left parenthesis OH right parenthesis straight I

therefore the compound D is n-propyl alcohol
