Question 1.

An optically inactive triglyceride produced two palmitic acid residues and one oleic acid residue, when heated in the presence of an acid. What is the structure(s) of the triglyceride(s) produced?

An illustration depicts the structures of two compounds. Compound 1 has a three-carbon vertical chain, in which C 1 is C H 2 O (C double bond O) (C H 2) 14 C H 3, C 2 is C H O (C double bond O) (C H 2) 14 C H 3, and C 3 is C H 2 O (C double bond O) (C H 2) 7 C H double bond C H (C H 2) 7 C H 3. Compound 2 has a three-carbon vertical chain, in which C 1 is C H 2 O (C double bond O) (C H 2) 14 C H 3, C 2 is C H O (C double bond O) (C H 2) 16 C H 3, and C 3 is C H 2 O (C double bond O) (C H 2) 14 C H 3.

Compound 3 has a three-carbon vertical chain, in which C 1 is C H 2 O (C double bond O) (C H 2) 14 C H 3, C 2 is C H O (C double bond O) (C H 2) 7 C H double bond C H (C H 2) 7 C H 3, and C 3 is C H 2 O (C double bond O) (C H 2) 14 C H 3. Compound 4 has a three-carbon vertical chain, in which C 1 is C H 2 O (C double bond O) (C H 2) 16 C H 3, C 2 is C H O (C double bond O) (C H 2) 14 C H 3, and C 3 is C H 2 O (C double bond O) (C H 2) 16 C H 3.

Question 2.

When heated in the presence of an acid, a triglyceride produced a linoleic acid residue, a palmitoleic acid residue, and an oleic acid residue. What is possible structures for this triglyceride?

An illustration depicts the structures of three compounds. Compound 1: a three-carbon vertical chain, in which C 1 is C H 2 O (C double bond O) (C H 2) 7 C H double bond C H C H 2 C H double bond C H (C H 2) 4 C H 3, C 2 is C H O (C double bond O) (C H 2) 7 C H double bond C H (C H 2) 5 C H 3, and C 3 is C H 2 O (C double bond O) (C H 2) 7 C H double bond C H (C H 2) 7 C H 3. Compound 2: a three-carbon vertical chain, in which C 1 is C H 2 O (C double bond O) (C H 2) 7 C H double bond C H C H 2 (C H 2) 6 C H 3, C 2 is C H O (C double bond O) (C H 2) 7 C H double bond C H (C H 2) 5 C H 3, and C 3 is C H 2 O (C double bond O) (C H 2) 7 C H double bond C H (C H 2) 7 C H 3. Compound 3: a three-carbon vertical chain, in which C 1 is C H 2 O (C double bond O) (C H 2) 7 C H double bond C H C H 2 C H double bond C H (C H 2) 4 C H 3, C 2 is C H O (C double bond O) (C H 2) 7 C H double bond C H (C H 2) 5 C H 3, and C 3 is C H 2 O (C double bond O) (C H 2) 7 C H 2 (C H 2) 5 C H 3.
