Question: Which reaction does not generally give a primary alcohol as a main product? (a) aldehyde +NaBH4 (b) epoxide +LiAlH4 (c) formaldehyde (H2C=O)+ Grignard reagent (d)

Which reaction does not generally give a primary alcohol as a main product? (a) aldehyde +NaBH4 (b) epoxide +LiAlH4 (c) formaldehyde (H2C=O)+ Grignard reagent (d) All of these generally give a primary alcohol as a main product. Regarding proton NMR spectroscopy, which statement (ad) is false? (a) Signals on the right (upfield) are due to relatively shielded protons. (b) The methyl protons of a simple ethyl group appear as a triplet. (c) Proton NMR does not destroy a sample that is being analyzed. The same sample can be run again and again if desired. (d) All of these statements are true
