WebChemical reactions, according to Dalton’s atomic theory, involve a rearrangement of atoms to form products. According to the postulates proposed by Dalton, the atomic structure comprised atoms, the smallest particle responsible for the chemical reactions to occur. The following are the postulates of his theory: Every matter is made up of atoms. WebDative bonding also known as co-ordinate bonding is a type of covalent bond in which sharing of electron takes place from the same atom. 3. Write an example of co-ordinate bonding. Answer: (1) Formation of Ammonium ion (2) Formation of Ammonia boron trifluoride (3) Formation of hydronium ion. 4. WebThe boiling point of butane is -0.5 o C and that of isobutane is -11.7 o C. The difference in the boiling points of these isomers can be accounted for by the stronger Van der Waals forces in the unbranched butane molecules (and the weaker Van der Waals forces in the short, branched isobutane molecules). Applications of Van der Waals Forces contract of mortgage
