Place the letter corresponding to the best choice in the blank to the left of the conversion. a. KMnO,H,O b. CHyl & 1. Mg ether 2. CO 3. Ho c. NaBH, ethano h. 1. NaCN 2. H,SO4, Ha, heat 2. H,o e. 1. CH,MgBr, ether i. Os, then Zn and HOAc 2. HO

Explanation / Answer

1) Name of the compound : 5-oxohexanoic acid

2) Correct order is : III < II < I < IV

If electron with drawing groups(NO2, Cl) on ring then acidity of benzoic acid increases.

If electron releasing groups (CH3, OH, NH2) on ring then acidity decreases.

4) Answer is : d) nitrile.

Nitrile (CN) is not a acyl(COCH3) derivative of carboxylic acid.

5) Answer : a) carbon atom with three bonds to an electronegative atom.
