Question

what type of intermolecular forces is/are present in ch3br? * 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:

1. London - Dispersion forces are present in all molecules as they result from temporary dipoles caused by the motion of electrons.
2. CH3Br is a polar molecule due to the difference in electronegativity between C - Br. The polar nature leads to dipole - dipole forces.
3. Hydrogen bonding occurs when H is bonded to N, O, or F. In CH3Br, H is bonded to C, so no hydrogen bonding. Also, CH3Br is a covalent compound, not ionic.

Answer:

C. London Dispersion forces and dipole - dipole forces
