AP Inter 2nd Year Chemistry Important Questions Lesson 6(c) Group-17 Elements<\/h2>\n

Very Short Answer Questions<\/span><\/p>\n

Question 1.
\nInterhalogen compounds are more reactive than the constituent halogens except for fluorine – Explain.
\nAnswer:
\nInter halogen compounds are more reactive than halogens. This is because X – X\u2019 bond in interhalogens is weaker than X \u2014 X bond in halogens except F – F bond.<\/p>\n

Question 2.
\nWhat is the use of ClF3<\/sub>?
\nAnswer:
\nClF3<\/sub> is very useful fluorinating agent and it is used for the production of VF6<\/sub> in the enrichment of U235<\/sup>.
\nU(s)<\/sub> + 3ClF3(l)<\/sub> \u2192 UF6(g)<\/sub> + 3ClF(g)<\/sub><\/p>\n

Question 3.
\nWhy are halogens coloured?
\nAn\u0161wer:
\nHalogens are coloured due to the absorption of radiations in visible region which results in the excitation of outer electrons to higher energy level. Halogens absorb different quanta of radiation and display different colours.<\/p>\n

Question 4.
\nWrite the reactions of F2<\/sub> and Cl2<\/sub> with water. (TS Mar. 17) (IPE Mar. \u201814)
\nAnswer:
\nFluorine produces O2<\/sub> and O3<\/sub> on passing through water.
\n3F2<\/sub> + 3H2<\/sub>O \u2192 6HF + O3<\/sub>
\n2F2<\/sub> + 2H2<\/sub>O \u2192 4HF + O2<\/sub><\/p>\n

Question 5.
\nElectron gain enthalpy of fluorine is less than that of chlorine – explain.
\nAnswer:
\nThe negative electron gain enthalpy of the fluorine is less than that of chlorine. This is due to small size of fluorine atom which results in strong inter electronic repulsions in the relatively small 2p orbitals of fluorine and thus the incoming electron does not experience much attraction.<\/p>\n

Question 6.
\nBond dissociation enthalpy of F2<\/sub> is less than that of Cl2<\/sub> – Explain.
\nAnswer:
\nBond dissociation enthalpy of F2<\/sub> is less than that of Cl2<\/sub>
\nExplanation:
\nIn F2<\/sub> molecule electron repulsions are greater among lone pairs because these lone pairs are much closer to each other than in case of Cl2<\/sub>.<\/p>\n

Question 7.
\nWrite the formulae of the compounds, in which oxygen has positive oxidation states and mention the oxidation states of oxygen in them.
\nAnswer:
\nIn OF2<\/sub> and O2<\/sub>F2<\/sub> oxygen has positive oxidation states.<\/p>\n
