Question

Which formula represents an asymmetrical molecule ch4 co2 n2 nh3

Answer 1

Answer:

NH₃  

Step-by-step explanation:

All the molecules have some degree of symmetry, but only NH₃ is asymmetric with respect to the bond dipoles.

NH₃ has a trigonal pyramidal geometry.

All the N-H bond dipoles point toward the N, so they all have an upward component with no counterbalancing downward component.

The bond dipoles do not cancel, so NH₃ has a molecular dipole.

CH₄ is tetrahedral and symmetrical.

CO₂  and N₂ are linear and symmetrical.
