The correct sequence of increasing covalent character is represented by [CBSE PMT 2005] A) \[LiCl Li + > Be2 + ) Let us help you simplify your studying. Which compound contains both ionic and covalent bonds? If #Δ"EN"# is large, the bond will have a small amount of covalent character. The covalent character increases in groups as we go from top to bottom.it decreases in periods as we go from left to right.it increases in groups as the electrons get further away from the nucleus the attractive forces bettween the positive charge of the nucleus and negative charge of the electrons decreases and they are easy to share with their atoms. See the answer. Smaller size and high ionisation energy, high electronegativity leads to more covalent character. Our videos will help you understand concepts, solve your homework, and do great on your exams. Our videos prepare you to succeed in your college classes. C ... < CH 3 COOH 6. This option is incorrect. On the basis of Fajan's rule, lower the size of cation higher will be its polarising power and higher will be the covalent character. The bond is covalent. Thus option 3 is the correct answer. As size of Li+ < Na+ < K+ < Rb+ < Cs+ the ionic character of LiCl < NaCl < KCl < RbCl < CsCl The order of increasing covalent character is: NaCl < MgCl2 < AlCl3 < SiCl4, because the charge on the cation increases ii. 600+ VIEWS.
