Inductive Effect and Dipole Moment: Molecular Attraction Revealed

The video tutorial explains the inductive effect and its impact on molecular polarity, dipole moments, bond lengths, and acidity. It highlights how the strength of the minus I group affects these properties, using examples like methyl chloride, methyl iodide, and various substituted acids. The tutorial also discusses the relationship between acidity, PKA values, and the distance of the minus I group from the acid group.

Which alkyl halide has the highest dipole moment due to its electronegativity?

• Methyl fluoride

• Methyl bromide

• Methyl chloride

• Methyl iodide

What effect does the strong minus I effect of fluorine have on the CF bond in methyl fluoride?

• Makes the bond non-polar

• Decreases bond length

• Increases bond length

• Has no effect on bond length

How does the minus I effect influence the bond length in methyl iodide?

• Makes the bond ionic

• Increases bond length

• Decreases bond length

• Has no effect on bond length

Which factor is directly proportional to the acidity of a compound?

• Distance of minus I group from acid group

• Electronegativity of the acid group

• Strength of minus I group

• PKA value

In the context of butyric acids, what happens to acidity as the distance between the minus I group and the acid group increases?

• Acidity decreases

• Acidity increases

• Acidity remains constant

• Acidity becomes unpredictable
