Question

Show how butanoic acid may be converted to each of the following compounds:

(a) 1-Butanol   

(b) Butanal 

(c) 1-Chlorobutane   

(d) Butanoyl chloride

(e) Phenyl propyl ketone

(f) 4-Octanone​

Answer 1

Answer:

(a) CH3CH2CH2COOH+ LiAlH4

= 1- butanol

(b) CH3CH2CH2COOH +SOCl2

= CH3CH2CH2COCl + H2(Pd/BaSO4)

= Butanal

(c)

CH3CH2CH2COOH+ LiAlH4

= 1- butanol+ PCl5 = 1-chlorobutane

(d) CH3CH2CH2COOH +SOCl2

= CH3CH2CH2COCl

(e)

CH3CH2CH2COOH +SOCl2

= CH3CH2CH2COCl + (C6H5)2Cd =

= C6H5COCH2CH2CH3

(f)

CH3CH2CH2COOH +SOCl2

= CH3CH2CH2COCl + (C4H9)2Cd =

= CH3CH2CH2COCH2CH2CH2CH3
