Which bond in the methylamine molecule (CH3NH2) is the most polar?
A
C–N
B
N–H
C
C–H
D
C–C
Verified step by step guidance1
Identify the bonds present in the methylamine molecule (CH\_3NH\_2): C–H, C–N, and N–H bonds.
Recall that bond polarity depends on the difference in electronegativity between the two atoms involved in the bond.
Look up the electronegativity values for the atoms: Carbon (C), Hydrogen (H), and Nitrogen (N).
Calculate the electronegativity differences for each bond: C–H, C–N, and N–H by subtracting the smaller electronegativity from the larger one.
Compare these differences; the bond with the greatest electronegativity difference is the most polar.
