Question

which of the following statements explains why the melting point of lauric acid is lower then the melting point of stearic acid?

Moving to another question will save this response The melting point of lauric aoa ???(CH2)10?O2? ts 43 Degree C The melting point of stearic acid ???(??2)1???2? is 69 Degree C Which of the following statements explans why the melting point of launc add Is lower than the melting point of stearic acid? Select only those responses that apply correctly Select ALL of the responses that apply; otherwise. no credit will be given Laurtc acids has less polai carboxylic acrt group than stearic acids. The London force interactions are stronger in stearc acid than they are in lauric acid. The hydrophobic tail of lauric acid is shorter than the hydrophobe tail of stearic acid. Stearic acid is a fatty acid whereas launc acid is not a fatty acid. Stearic acid is soluble in water and laiKic acid is not soluble in water. Moving to another question we save this response

Explanation / Answer

In lauric acid there are 11 CH2 groups but in stearic acid there are 17 CH2 groups so the number of CH2 groups in stearic acid is more than that of lauric acid.So the surface area increases there by we have to supply more energy to breack all the bonds than that of , which increases the melting point.

So the correct answer is The hydrophobic tail of lauric acid is shorter than the hydrophobic tail of stearic acid.
