Question

Which is NOT considered a commonly used reagent for conversion of alcohols to alkyl halides? HCl PBr_3 CH_3OH SOCl_2 The reactions of alcohols have mainly to do with the following: The oxygen atom of the hydroxyl group is nucleophilic and weakly basic The hydrogen atom of the hydroxyl group is weakly acidic. The hydroxyl group can be converted to a leaving group so as to allow substitution or elimination reactions. Alcohols are strong acids. Which is NOT true about carbonyl compounds? The C=O bond consists of 2 electrons in a sigma bond and 1 electron in a pi bond. The carbonyl carbon atom is sp 2 hybridized. The carbonyl group is trigonal planar. The oxygen atom is highly polarized and bears a substantial negative charge while the carbonyl carbon bears a substantial positive charge.

Explanation / Answer

14. Answer is c CH3OH (metanol). Methanol is an alcohol itself.

15. Answer is c. ( OH can be converted to OTs, OMs or Br/I etc. for substitution reaction.)

16. Answer is a. (1 electron pi bond is not possible).
