Explanation

`{:(underset(3-"Hydroxybutanoic acid")(CH_(3)-overset(OH)overset(|)(CH)-CH_(2)-COOH)+CH_(3)-underset(3-"Hydroxypentanoic acid")(CH_(3)-overset(OH)overset(|)(CH)-CH_(2)-COOH)),(" "darr-(2n-1)H_(2)O),(" "(O-underset(R)underset(|)(CH)-CH_(2)-underset(O)underset(||)(C)-O-underset(R)underset(|)(CH)-CH_(2)-underset(O)underset(||)(C))):}`
`R=CH_(3)^(-), C_(2)H_(5)^(-)`
