Question

4) An important characteristic of an oxidation-reduction (Redox) reaction is: a) The transfer of an electron from one reactant to another b) A chemical conversion c) That a salt forms as a product d) That oxygen is present 5) One of the major differences between organic and inorganic chemistry, is that organic chemistry deals with the chemistry of compounds containing carbon and hydrogen, whereas inorganic chemistry does not concern itself with the reaction of carbon a) True b) False c) Only for redox reactions

Explanation / Answer

4) a) The transfer of an electron from one reactant to another

Explanation: In redox reactions there are two types of reactants-the oxidizing agent and the reducing agent.The oxidizing agent is the reactant that loses electrons and itself gets reduced,and the reducing agent is the reactant that gains electrons and itself gets oxidized.The oxidation number (degree of oxidation or loss of electrons) of the species increases on oxidation and decreases on reduction

example:H2+F2-->2HF

oxidation: H2 --->2H+ +2e-

reduction:F2+2e--->2F-

5) a)true

organic chemistry deals with hydrocarbons ,long chain compounds made from carbon and hydrogen.
