The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that CCl₄ (carbon tetrachloride) is a non-polar molecule. ### Step 2: Analyze the Structure of CCl₄ CCl₄ has a tetrahedral geometry due to the sp³ hybridization of the carbon atom. In this structure, the carbon atom is at the center with four chlorine atoms at the corners of a tetrahedron. ### Step 3: Identify the Nature of the Bonds The bonds between carbon and chlorine (C-Cl) are polar bonds because chlorine is more electronegative than carbon. This means that each C-Cl bond has a dipole moment, with chlorine carrying a partial negative charge (δ-) and carbon carrying a partial positive charge (δ+). ### Step 4: Assess the Overall Polarity Even though CCl₄ has polar bonds, the symmetrical tetrahedral shape of the molecule causes the dipole moments of the four C-Cl bonds to cancel each other out. This cancellation results in a net dipole moment of zero for the entire molecule, making CCl₄ non-polar. ### Step 5: Evaluate the Reason The reason states that CCl₄ has polar bonds. This statement is true; however, it does not explain why CCl₄ is non-polar. The reason does not account for the symmetry of the molecule and the cancellation of dipole moments. ### Conclusion Both the assertion and the reason are true, but the reason is not the correct explanation for the assertion. Therefore, the correct option is that the assertion is true, the reason is true, but the reason is not the correct explanation for the assertion. ### Final Answer Assertion: True Reason: True Correct Option: Assertion is true, Reason is true, but Reason is not the correct explanation for Assertion. ---
