Write word and symbol equations for each of the reactions seen in the experiment. Predict the location of fluorine in this activity series. Fluorine is the most reactive while tenessine is the least reactive. However, if the same acid is added to zinc (Zn) then bubbles will be produced more quickly. F>Cl>Br> I this because the attraction of the electrons decreases with the distance of the nucleus to the electrons and since this distance increases from F to I , the reactivity decreases from F to I They also have an order of reactivity that is the opposite of the metals in groups 1 and 2. Ask Question Asked 2 years, 11 months ago. Then, list the halogens in order of decreasing ease of reduction. Learn more about the properties of halogens in this article. Chlorine is more reactive than iodine so will take its place in the molecule, resulting in the formation of potassium chloride and iodine. Log in. Electronegativity is the power of an atom to pull electrons toward itself, which usually forms a bond with another atom and thus creates a molecule. asked Nov 13, 2019 in Chemistry by KalpnaSingh (66.3k points) p - block elements; class-12; 0 votes. Another example of halogen elements reactivity are the interaction of halogens with water . Join now. An interhalogen compound is a molecule which contains two or more different halogen atoms (fluorine, chlorine, bromine, iodine, or astatine) and no atoms of elements from any other group.. Active 3 months ago. The melting and boiling points of the halogens increase as you increase atomic number (as you move down the periodic table). An example is the addition of chlorine to a solution of potassium iodide. Their formulae are generally XY n, where n = 1, 3, 5 or 7, and X is the less electronegative of the two halogens. The order of reactivity of ... chemistry. Answered By . The halogens, group 7, are an important group of elements both chemically and socially. answr. Try the given examples, or type in your own problem and check your answer with the step-by-step explanations. Answered Decreasing order of reactivity of halogen towards alkanes is 2 See answers Priyangsri Priyangsri Answer:hey. The elements change their state of matter at room temperature and pressure as you increase atomic number. Compare your reactivity series with group 7 in the periodic table – what do you notice? Explain the order of reactivity of halogen acids towards alcohol 1 See answer rajlakshya250 is waiting for your help. 1) I can only answer this question .the most reactive halogen is fluor and the reactivity decreases in that order. In case of reactivity the HI will be the most reactive and then HBr and least reactive will be the HCl. Most interhalogen compounds known are binary (composed of only two distinct elements). Explaining trends in reactivity. When compared, the lists are identical. The correct order of reactivity in SNI reaction for the following compounds is. Log in. This is due to the fact that the reducing character of Iodine is highest and it can easily break the H-I bond and thus can react faster. How do the two lists correlate? Add your answer and earn points. We call this type of a reaction a displacement reaction. Answers and Replies Related Chemistry News on Phys.org.
