Which of the following will be obtained by the reduction of pentanal?

Question

a) pentene

b) 1-pentanol

c) 2-pentanol

d) 3-pentanol

Answer 1

If by pentanal you mean a terminal  =O group at one end of a linear 5 carbon chain, then the reduction product would open the double bond and add hydrogen giving an -OH  group resulting in b) .....1-pentanol

CH3CH2CH2CH2CH=O  + H2  ---> CH3CH2CH2CH2CH2OH

Answer 2

pentanal is not pentanol, check spelling
