Which formula represents an asymmetrical molecule ch4 co2 n2 nh3
1 answer:
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 <em>symmetrical</em>.
