Thus flourine is most electronegative while iodine is least in halogens. b) … It would be "BeCl"_2. Ans: (a) Li I. (ii) smaller the size of anions. According to Fajan’s rule, smaller the cation, bigger the anion, more is the covalent characters. Why Lithium iodide is more covalent in character than Lithium chloride? Among LiC1, Becl , BCI and CCI the covalent bond character follows the order: 1) … AICI 3 is considered to show maximum covalent character among the given compounds. (i) larger the charge on the ions. polar covalent bond: A covalent bond that has a partial ionic character to it, as a result of the difference in electronegativity between the two bonding atoms. CHEMICAL BONDING 43. (ii) smaller the size of anions. Why is LiI more covalent than LiF? NaI will be having maximum covalent character. For which of the following hybridisation the bond angle is maximum ? Percentage covalent character is maximum in: (A) BeX2 (B) MgX2 (C) CaX2 (D) SrX2 . 1. (iv) larger the polarizing power larger the covalent character.AlCl3 will show Maximum covalent character on account of the higher polarising power of Al3+ because of its having higher positive charge and smaller size. In this case, iodine is … Percentage covalent character is maximum in: (A) BeX2 (B) MgX2 (C) CaX2 (D) SrX2 . 10.4k VIEWS. electronegativity: A measure of the tendency of an atom to attract electrons to itself. Answer: (d) AlCl 3 Explanation: We know that, extent of polarisation ∝ covalent character in ionic bond. 2:15 000+ LIKES. PARTICLE NATURE OF ELECTROMAGNETIC RADIATION AND P... QUANTUM NUMBERS (Principal, Azimuthal, Magnetic an... Mendeleev's Periodic Table Merits and De-merits, SETS (Collection of well defined objects). Sie können Ihre Einstellungen jederzeit ändern. aus oder wählen Sie 'Einstellungen verwalten', um weitere Informationen zu erhalten und eine Auswahl zu treffen. Thus, the metal highest on the periodic table (s-block, first two columns) will have an electronegativity closest to that of "Cl". NaCl This is because Al 3 + bears 3 unit of positive charge and shows strong tendency to distort the electron cloud, thus the covalent character in Al-CI bond dramatically increases. Maximum number of covalent bonds by which two atoms can be bonded to each other 1) Four 2) Two 3) Three 4) No fixed number 18. Which of the following atoms has miniumum covalent radius . The bigger the size of … Among the following the maximum covalent character is shown by the compound (1) M g C l 2 (2) F e C l 2 (3) S n C l 2 (4) A l C l 3. Which of the following has the highest covalent character? Which of the following is not correct resonating structure for carbon dioxide ? 16. A NaCl B K2O C H2O D MgO. Books. (a) s p² (b) s p³ (c) s p (d) d s p². Which of the following has maximum covalent character? Answer: (d) AlCl 3 Explanation: We know that, extent of polarisation ∝ covalent character in ionic bond. Ionic character can be determined by comparing the electronegativity (EN) of the two elements in each compound. Out of the following compounds, which has the maximum covalent character? Among the following the maximum covalent character is shown by the compound : (1) AlCl 3 (2) MgCl 2 (3) FeCl 2 (4) SnCl 2. In the given case, the cation is common. Among the following the maximum covalent character is shown by the compound (a) MgCl 2 (b) FeCl 2 (c) SnCl 2 (d) AlCl 3. Solution: Al +3 is having highest polarizing power than other compounds having greater covalent character. 10.4k SHARES. (a) Li I (b) Li F (c) Li Cl (d) Li Br. Dazu gehört der Widerspruch gegen die Verarbeitung Ihrer Daten durch Partner für deren berechtigte Interessen. The electronegativity, just like ionization energy, increases from the bottom-left to upper-right of the periodic table. Among these 3 BeCL2 has the greatest covalent character. CaCl2 5. … A) Option 1: B) Option 2: C) Option 3: D) Option 4: Answer: D) Option 4 Explanation: According to Fajans rule, cation with greater charge and smaller size favours covalency. Which of the following has directional character? Which of the following has more covalent character? Solution : being smaller has highest polarising power according to Fazan rules. Which of the following chloride has considerablecovalent character ? 26) Which has maximum covalent character ? Among the following, the maximum covalent character is shown by the compound. MgCl2 4. This produces an ionic bond with covalent character. MgCl2 4. Which of the compounds below has bonds with the most covalent character?
