Explain the answer in detail..... Q.2. Among LiI, NaI and KI, the one which is more ionic and more soluble in water is : (a) KI (b) NaI (c) LiI (d) None of these Share with your friends Share 1 Vartika Jain answered this Dear Student, As we move down the group, the size of ion increases. So, amongst LiI, NaI and KI, KI will have the largest size of cation i.e. K+Also, we know thatPolarisation α 1size of cationSo, greater the size of cation, less is the polarisation and lesser will be the covalent character. Therefore, KI will be more ionic. Now, greater the ionic character greater will be the polarity and so greater will be the solubility. Hence, correct answer is (a) 1 View Full Answer Praveen answered this (c) 3 Shreya Yadav answered this its small size, the lithium ion has a higher polarising power than the potassium ion. It polarises the electron cloud of the iodide ion to a much greater extent than the potassium ion. This causes a greater covalent character in LiI? 1
