In ionic bonding, metals transfer electrons to non-metals. Li loses an electron to form a cation (Li\u207a), while F gains the electron to form an anion (F\u207b), resulting in an ionic bond.<\/p>\n\n\n\n<p>b. <strong>CF\u2084<\/strong> \u2013 <strong>Covalent Bonding<\/strong><br>Carbon (C) and fluorine (F) are both non-metals. In covalent bonding, non-metals share electrons. In CF\u2084, carbon shares electrons with fluorine atoms to form covalent bonds.<\/p>\n\n\n\n<p>c. <strong>CaO<\/strong> \u2013 <strong>Ionic Bonding<\/strong><br>Calcium (Ca) is a metal, and oxygen (O) is a non-metal. Calcium donates two electrons to form a Ca\u00b2\u207a cation, while oxygen accepts those electrons to form an O\u00b2\u207b anion, creating ionic bonds.<\/p>\n\n\n\n<p>d. <strong>NH\u2083<\/strong> \u2013 <strong>Covalent Bonding<\/strong><br>Nitrogen (N) and hydrogen (H) are non-metals, and they form covalent bonds by sharing electrons.

Copper loses two electrons to form Cu\u00b2\u207a ions, while chlorine gains one electron per atom to form Cl\u207b ions, resulting in ionic bonds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Solubility Order:<\/h3>\n\n\n\n<p>To arrange the solubility in water, it is important to consider the type of bonds, polarity, and lattice energy of the compounds. Ionic compounds tend to be more soluble in water due to their polarity and ability to dissociate into ions. Covalent compounds that can form hydrogen bonds (like alcohols or simple sugars) can also be soluble, but non-polar covalent compounds are usually less soluble.<\/p>\n\n\n\n<p>From the image link you provided, here is the expected solubility order (least soluble to most soluble):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>CaSO\u2084<\/strong> (least soluble)<\/li>\n\n\n\n<li><strong>Na\u2082SO\u2084<\/strong><\/li>\n\n\n\n<li><strong>NaCl<\/strong><\/li>\n\n\n\n<li><strong>KNO\u2083<\/strong> (most soluble)<\/li>\n<\/ul>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>CaSO\u2084<\/strong> is the least soluble because calcium sulfate has a high lattice energy, meaning it takes a lot of energy to break the bonds between ions, reducing its solubility.<\/li>\n\n\n\n<li><strong>Na\u2082SO\u2084<\/strong> is more soluble due to the smaller size and lower lattice energy of sodium ions compared to calcium, which helps it dissociate more easily in water.<\/li>\n\n\n\n<li><strong>NaCl<\/strong> is highly soluble in water because sodium chloride dissociates easily into Na\u207a and Cl\u207b ions, which are stabilized by the polar water molecules.<\/li>\n\n\n\n<li><strong>KNO\u2083<\/strong> is the most soluble among these compounds because potassium nitrate dissociates completely in water with a relatively low lattice energy and high hydration energy, enhancing its solubility.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>State whether the following compounds have ionic or covalent bonding: a LiF b CF4 c CaO d NH3 e PCl3 f CuCl2 Arrange the following sets in order of solubility in water (least soluble first): The Correct Answer and Explanation is : Ionic or Covalent Bonding: a.
