PAPER ONE: MULTIPLE CHOICE QUESTIONS TYPE ONE QUESTIONS Questions 1-33 DIRECTIONS: Each of the following questions or incomplete statements below is followed by four suggested answers lettered A - D. Select or choose the letters of te best answer to the question or incomplete statement. Which one of the following reagents is most suitable for converting 1. OCH Br B) NaBrO (aq) D) CH Br() O-CHOH into A) NaBr(aq) C) PBr () For a given alkyl group R attached to a halogen the iodo - compound reacts most readily followed by the bromo-compound and then the chloro compound, react least readily. This is because: A) Chloro-compounds are more polar than lodo-compounds. B) elecronegativity dacreases down the group C) the C- CI bond is stronger than the C- I bond D) the chlorine atom is smaller than the 2. iodine atom. Which one of the following reagents is most suitable for converting CH CH,CH Br into CH CH CH OCH,CH,? A) CH CH COCI BỊ dry CH CH COO Ag C) CH CH OH D) CH,CH,O Na' in ethanol 3. 4. 1- bromo propane can be converted into 2- brompropane in a two - stage reaction. Which one of the following pairs of reagents can be used in succession for this conversion? A) aqueous NaOH, P(s/Br(1) B) alcoholic NaOH, Br (1) C) aqueous NaOH, conc.HBr D) alcoholic NaOH, conc.HBr
