Will acid react with hydrogen, bromine and hydrogen bromide? 1.acetic 2.propionic 3.stearic 4.oleic

The reactions of organic acids with hydrogen, bromine and hydrogen bromide can proceed by the addition type, and with bromine and hydrogen bromide by the substitution type. To react with all of the listed substances, the acid must contain unsaturated bonds. Of the presented unsaturated is oleic acid – C17H33COOH.

Let us write down the illustrating reaction equations:

1.CH3 (CH2) 7CH = CH (CH2) 7COOH + H2 → C17H35COOH;

2. CH3 (CH2) 7CH = CH (CH2) 7COOH + Br2 → CH3 (CH2) 7CH (Br) CH (Br) (CH2) 7COOH;

3. CH3 (CH2) 7CH = CH (CH2) 7COOH + HBr → CH3 (CH2) 7CH (Br) (CH2) 8COOH.
