Question

question 43 liquid fats called oils contain a. ring structures b. fat molecules lined up side - by - side c. more hydrogen atoms than hard fats d. long ch 2 chains linked by double covalent bonds and are often \kinked\

Explanation:

Liquid oils are unsaturated fats. Their fatty - acid chains have long CH₂ chains linked by double covalent bonds, which cause kinks in the chains. This prevents them from packing tightly together, resulting in a liquid state at room temperature. Ring structures are not characteristic of liquid fats in general. Fat molecules lined up side - by - side is more typical of saturated fats. Liquid oils have fewer hydrogen atoms than saturated (hard) fats due to the presence of double bonds.

Answer:

D. long CH₂ chains linked by double covalent bonds and are often "kinked"
