Question

what type of intermolecular forces is/are present in c3h8? * london dispersion forces only dipole - dipole forces only london dispersion forces and dipole - dipole forces dipole - dipole and hydrogen bonding dipole - dipole, hydrogen bonding, and london dispersion forces ionic ionic and london dispersion forces

Explanation:

Step1: Analyze molecular polarity

Propane ($C_3H_8$) is a non - polar molecule. The electronegativity difference between carbon and hydrogen is small, and the molecule has a symmetrical structure.

Step2: Identify intermolecular forces

Non - polar molecules only exhibit London dispersion forces. London dispersion forces are present in all molecules due to temporary fluctuations in electron distribution. Dipole - dipole forces occur in polar molecules, and hydrogen bonding occurs when hydrogen is bonded to a highly electronegative atom (N, O, F). Since $C_3H_8$ is non - polar, there are no dipole - dipole forces or hydrogen bonding.

Answer:

London Dispersion Forces only
