Concept explainers
Interpretation:
The nature of the molecule that contains polar bonds has to be chosen from the given options.
Concept Introduction:
Measure of the degree of inequality in attraction of the bonding electrons to the various locations present within a molecule is known as molecular polarity. This can also be said in terms of electron attraction and that is in a molecule one part is favored than the other parts of the molecule.
If in a molecule there is an uneven distribution of electronic charges means it is known as polar molecule. If there is a symmetrical distribution of electron charge over the molecule means it is known as nonpolar molecule. Two factors that decide molecular polarity is bond polarity and geometry of molecule. If a molecule is symmetrical means then there won’t be any molecular polarity because the effect given by the polar bonds may cancel out each other.

Reset Help In the gas phase, (CH3)2N is a stronger Lewis base than is CH3NH₂ because the N-H bond is more polar than the N-C bond, making the lone pair on the N atom more accessible to the H+ that needs to be added. In the liquid phase, the steric hindrance from the size of the CH3 groups becomes more pronounced, making the N atom less accessible to the H+ ion.arrow_forward
