- Show the mechanism steps to obtain the lowerenergy intermediate: *see imagearrow_forwardSoap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups.
