Few pairs of molecules are given below. Which bond of the molecule of ...
Explanation:
To determine the polarity of a bond, we need to consider the electronegativity difference between the two atoms involved in the bond. A greater electronegativity difference indicates a more polar bond.
(i) H3C - H, H3C - Br:
The electronegativity of H is 2.1 and the electronegativity of Br is 2.8. The electronegativity difference between H and Br is 0.7. Therefore, the H3C - Br bond is more polar than the H3C - H bond.
(ii) H3C-NH2, H3C-OH:
The electronegativity of N is 3.0 and the electronegativity of O is 3.5. The electronegativity difference between N and H is 0.5, and the electronegativity difference between O and H is 0.4. Therefore, both the H3C-N and H3C-O bonds are equally polar.
(iii) H3C-OH, H3C-SH:
The electronegativity of O is 3.5 and the electronegativity of S is 2.5. The electronegativity difference between O and H is 0.4, and the electronegativity difference between S and H is 0.6. Therefore, the H3C-S bond is more polar than the H3C-O bond.
(iv) H3C-Cl, H3C-Br:
The electronegativity of Cl is 3.0 and the electronegativity of Br is 2.8. The electronegativity difference between Cl and H is 0.1, and the electronegativity difference between Br and H is 0.3. Therefore, the H3C-Br bond is more polar than the H3C-Cl bond.
Summary:
Based on the electronegativity differences, the order of increasing polarity for the given pairs of molecules is:
(i) H3C - H < h3c="" -="" />
(ii) H3C-NH2 = H3C-OH
(iii) H3C - OH < h3c="" -="" />
(iv) H3C - Cl < h3c="" -="" />
Therefore, the correct answer is option 'b': C-Br, C-O, C-O, C-Cl.
To determine the polarity of a bond, we need to consider the electronegativity difference between the two atoms involved in the bond. A greater electronegativity difference indicates a more polar bond.
(i) H3C - H, H3C - Br:
The electronegativity of H is 2.1 and the electronegativity of Br is 2.8. The electronegativity difference between H and Br is 0.7. Therefore, the H3C - Br bond is more polar than the H3C - H bond.
(ii) H3C-NH2, H3C-OH:
The electronegativity of N is 3.0 and the electronegativity of O is 3.5. The electronegativity difference between N and H is 0.5, and the electronegativity difference between O and H is 0.4. Therefore, both the H3C-N and H3C-O bonds are equally polar.
(iii) H3C-OH, H3C-SH:
The electronegativity of O is 3.5 and the electronegativity of S is 2.5. The electronegativity difference between O and H is 0.4, and the electronegativity difference between S and H is 0.6. Therefore, the H3C-S bond is more polar than the H3C-O bond.
(iv) H3C-Cl, H3C-Br:
The electronegativity of Cl is 3.0 and the electronegativity of Br is 2.8. The electronegativity difference between Cl and H is 0.1, and the electronegativity difference between Br and H is 0.3. Therefore, the H3C-Br bond is more polar than the H3C-Cl bond.
Summary:
Based on the electronegativity differences, the order of increasing polarity for the given pairs of molecules is:
(i) H3C - H < h3c="" -="" />
(ii) H3C-NH2 = H3C-OH
(iii) H3C - OH < h3c="" -="" />
(iv) H3C - Cl < h3c="" -="" />
Therefore, the correct answer is option 'b': C-Br, C-O, C-O, C-Cl.
