Which of the following are the characteristics of Transition Elements?
Form coloured salts, have catalytic properties
React with water to form alkaline solution, have different oxidation state
Form different charges, exist as diatomic molecules
High melting & boiling point, soft
What is the type of chemical bond formed by hydrogen and chlorine?
Dative bond
Hydrogen bond
Covalent bond
Ionic bond
Metallic bond
Most of the organic compounds do not soluble in water. Ethanol as one of the organic compound however it soluble in water readily. Why?
Because it is colourless and easily mix with water
Because the weak van der Waals's forces easily break down and combine with water molecules
Because ethanol form dative bond with water molecule due to the strong attraction between partial positive charge of water and partial negative charge of ethanol
Because the formation of hydrogen bond between partial negative O in ethanol with partial positive H in water molecule
Ionic compounds have higher melting and boiling point than that of covalent compound, because...
the strong electrostatic forces of attraction between the oppositely charge ions in ionic compound are difficult to be broken
the ionic compounds are held by strong metallic bond
the present of hydrogen bond between the ions in ionic compound
the gigantic structure of ionic compounds have stronger van der Waals' forces of attraction
