Step-1
Dehyrogenation of propan-1-Ol to propanal by passing its vapor over heated Cu (573K)
$C H_{3} C H_{2} C H_{2} O H C u / 573 K - ---- \to C H_{3} C H_{2} C H O$ $CH_3CH_2CH_2OHstackrel(Cu"/"573K)-> CH_3CH_2CHO$

Step-2

Treatment of propanal with $H C N$ $HCN$ to produce 2-hydroxybutanenitrile

$C H_{3} C H_{2} C H O H C N - - \to C H_{3} C H_{2} C H (O H) C N$ $CH_3CH_2CHOstackrel(HCN)-> CH_3CH_2CH(OH)CN$

Step-3

Acid hydrolysis of 2-hydroxybutanenitrile to 2-hydroxybutanoic acid.

$C H_{3} C H_{2} C H O H C N H_{3} O^{+} - -- \to C H_{3} C H_{2} C H (O H) C O O H$ $CH_3CH_2CHOHCNstackrel(H_3O^+)-> CH_3CH_2CH(OH)COOH$
