which compound would most likely experience only london dispersion forces between its molecules?
a) no₂
b) sf₄
c) nf₃
d) h₂co
e) ccl₄

Explanation:

London dispersion forces are the only intermolecular forces in non - polar molecules.

• \(NO_2\) is polar due to its bent shape and the difference in electronegativity between \(N\) and \(O\).
• \(SF_4\) has a see - saw shape and is polar.
• \(NF_3\) has a trigonal pyramidal shape and is polar.
• \(H_2CO\) (formaldehyde) is polar.
• \(CCl_4\) has a tetrahedral shape. Since all the \(C - Cl\) bonds are equivalent and symmetrically arranged, the dipole moments cancel out, making \(CCl_4\) non - polar.

Answer:

e) \(CCl_4\)
