b) ---Select---A ketoneBoth a ketone and an aldehydeAn aldehydeNeither a ketone nor an aldehyde will yield a 2o alcohol when reactedwith LiAlH4 followed by anacid workup.
c) ---Select---An aldehydeBoth a ketone and an aldehydeA ketoneNeither a ketone nor an aldehyde will yield a 2o alcohol when reactedwith H2 in the presence of ametal catalyst.
d) ---Select---A primary alcoholA secondary alcoholBoth a primary and secondary alcoholNeither a primary nor secondary alcohol can yield a carboxylic acid when reacted withchromic acid in the presence of water
e) ---Select---Neither a ketone nor an aldehydeA ketoneBoth a ketone and an aldehydeAn aldehyde will result from a reaction of a3o alcohol with PCC.
f) ---Select---Both a ketone and an aldehydeNeither a ketone nor an aldehydeAn aldehydeA ketone will yield a 2o alcohol when reactedwith Grignard reagent followed by an acid workup.
Explanation / Answer
A) A ketones (2y alcohols oxidize into ketones) B) A ketone (ketones reduce into 2y alcohols) C) A ketone D) A primary alcohol (1y alcohols and aldehydes oxidizeinto carboxylic acids, especially under "moist" conditions) E) Neither an aldehyde or a ketone (3y alcoholscannot be oxidized due to lack of hydrogens on thecarbinol) F) Aldehydes (they yield 2y alcohols with an increase innumber of carbons in grignard reactions)
