Question 1

Which of the following statements best explains why the C–F bond is highly polarized, based on the electronegativity values shown in the image?

Accepted Answer

Because fluorine has a much higher electronegativity than carbon, causing electrons to be drawn toward fluorine.

Question 2

Given the electronegativity values, which bond is expected to be the most polar?

Accepted Answer

$$\mathrm{C-F}$$

Question 3

Which of the following molecules would have the greatest dipole moment, assuming all bonds are single bonds?

Accepted Answer

$$\mathrm{CH_3F}$$

Question 4

Based on the periodic trend shown in the image, which element would you expect to have the strongest -I (negative inductive) effect when attached to a carbon chain?

Accepted Answer

Fluorine

Question 5

Which of the following statements about the inductive effect is correct, considering the electronegativity values?

Accepted Answer

The inductive effect decreases as the electronegativity difference between bonded atoms decreases.

Question 6

Which of the following compounds would have the most acidic hydrogen, based on the electronegativity of the substituent attached to the carbon?

Accepted Answer

$$\mathrm{FCH_2COOH}$$

Question 7

Which of the following best describes the trend in electronegativity across a period and down a group, as shown in the image?

Accepted Answer

Electronegativity increases across a period and decreases down a group.

Question 8

Which of the following bonds would be considered nonpolar based on the electronegativity values provided?

Accepted Answer

$$\mathrm{C-H}$$

Question 9

If a molecule contains a C–Cl bond, what can be inferred about the bond polarity?

Accepted Answer

The bond is polar, with chlorine being partially negative.

Question 10

Which of the following statements is true regarding the effect of electronegativity on the stability of carbocations?

Accepted Answer

Carbocations are stabilized by adjacent atoms or groups with lower electronegativity due to their electron-donating inductive effect.
