The reaction of a Grignard reagent with a carboxylic acid does not give a secondary alcohol. This is because (a) Grignard reagents only react with the aldehydes, ketones, esters and epoxides. (b) The carboxylic acid is too sterically hindered to react. (c) The carboxylic acid is not electrophilic enough to react. (d) The Grignard reagent is a base, so an acid-base reaction occurs.
Grigoriy S.
25- The product of a Grignard reaction with CO2 is an alpha-hydroxy carboxylic acid. Select one: a- true b- false
Adi S.
Answer true or false. (a) Aldehydes and ketones are polar compounds. (b) Aldehydes have lower boiling points than alcohols with comparable carbon skeletons. (c) Low-molecular-weight aldehydes and ketones are very soluble in water. (d) There is no possibility for hydrogen bonding between molecules of aldehydes and ketones.
