Final answer:
Yes, 2-acetyltoluene has dipole-dipole interactions due to its permanent dipole from the polar carbonyl group and the methyl group on the aromatic ring.
Step-by-step explanation:
The student has asked whether 2-acetyltoluene has dipole-dipole interactions. The molecular dipole moment in a molecule depends on the arrangement of the individual bond dipoles and their directions. Since 2-acetyltoluene contains a polar carbonyl group (C=O) as part of its acetyl moiety and a methyl group on the aromatic ring, these groups have different electronegativities, and their geometrical arrangement does not lead to complete cancellation of the dipoles. Consequently, 2-acetyltoluene will exhibit a permanent dipole, and thus, the most significant intermolecular force present in this substance is dipole-dipole interaction.
