Solution

$C_{4} H_{8} O$
1) $C H_{3} - C H_{2} - C | | O - C H_{3}$ &
2) Ref. Image
3) $C H_{3} - C H_{2} - C H_{2} - C H O$
Three possible isomers.
IUPAC NAME
1) Butane 2-one
2) 2, methyl proponal
3) Butanal
Method of preparation
1) oxidation of primary and secondary alcohols
$C H_{3} C H_{2} C H_{2} - O H K_{2} C r_{2} O_{7} - ---- \to H_{2} S O_{4} C H_{3} C H_{2} C H_{2} C H O$
$C H_{3} - O H | C H - C H_{2} - C H_{3} P C C - -- \to C u C H_{3} - O | | C - C H_{2} - C H_{3}$
2) Dehydrogenation of Alcohols
$C H_{3} C H_{2} C H_{2} C H_{2} - O H C u / 573 k - ---- \to C H_{3} C H_{2} C H_{2} C H O + H_{2}$
