Answer 1

The product for the following reaction are :

• 2 - butanone
• CH₃CH₂COCl
• CH₃CH₂CONHCH₃

T carboxylic acid is an organic compound. the functional group of carboxylic acid is carboxy. general formula is given as : R - COO⁻.

The reactions are given as follows :

1) the reduction of carboxylic acid into ketone with the organometallic compound is given as follows :

CH₃CH₂COOH     +  CH₃Li   ------>   CH₃CH₂COCH₃

                                                                  2 butanone

2) the reaction of carboxylic acid with SOCl₂ is given as follows :

CH₃CH₂COOH    +   SOCl₂   ----->   CH₃CH₂COCl

3) the reaction of carboxylic acid with CH₃NH₂ is given as follows

CH₃CH₂COOH  +   CH₃NH₂   ----->   CH₃CH₂CONHCH₃

Thus,  The product for the following reaction are :

• 2 - butanone
• CH₃CH₂COCl
• CH₃CH₂CONHCH₃
