(A): NaCl is ionic whereas AlCl3 is covalent (R): Greater charge on cation increases covalent character A Both A and Rare true and R is the correct explanation of A Both A and Rare true but Ris not the correct explanation of A A is true but Ris false A is false but R is true |
| Answer» <html><body><p><strong>Answer:</strong></p><p>NaCl is more <a href="https://interviewquestions.tuteehub.com/tag/ionic-1051191" style="font-weight:bold;" target="_blank" title="Click to know more about IONIC">IONIC</a> than AlCl3. In NaCl, both Na and Cl will have an equal <a href="https://interviewquestions.tuteehub.com/tag/charge-914384" style="font-weight:bold;" target="_blank" title="Click to know more about CHARGE">CHARGE</a>. In AlCl3, the charge of the cation Al3+ is higher when compared to Na+ while the anion Cl is the same in both the compounds. Therefore, <a href="https://interviewquestions.tuteehub.com/tag/according-366619" style="font-weight:bold;" target="_blank" title="Click to know more about ACCORDING">ACCORDING</a> to Fajan's rule, AlCl3 is more covalent than NaCl.so A is correct .</p><p></p><p></p><p>The covalent character <a href="https://interviewquestions.tuteehub.com/tag/always-373607" style="font-weight:bold;" target="_blank" title="Click to know more about ALWAYS">ALWAYS</a> increases down the <a href="https://interviewquestions.tuteehub.com/tag/group-1013370" style="font-weight:bold;" target="_blank" title="Click to know more about GROUP">GROUP</a>. This is because as the electron cloud moves further away from the nucleus of the atom,it becomes easier to share the electrons with other atoms. And so the covalent character always decreases across a period..so this is also true </p><p><strong>Explanation:</strong></p><p>so both a and r are true and r the correct explaination of a</p></body></html> | |
