True and False questions!!
1. True and False Question (1) Carbonyl compounds have higher boiling points than hydrocarbons, but lower boiling points than corresponding alcohols. (2) Aldehydes and ketones react with primary amines to form imines and with secondary amines to form enamines. (3) Aldehydes and ketones can be oxidized to carboxylic acids. (4) Diols can form acetal with the ketone or aldehyde to protect them for selective reduction of the ester (5) The electron-withdrawing group in Wittig reagent does...

Three bottles A, B, and C have been found, each of which contains a
liquid and is labeled \"amine C8H11N.\" As an expert in amine
chemistry, you have been hired as a consultant and asked to
identify each compound. Compounds A and B give off a gas when they
react with NaNO2 and HCl at 0 ℃; C does not. However, when the
aqueous reaction mixture from the diazotization of C is warmed, a
gas is evolved. Compound A is...

Organic compound X, with molecular formula C11H1403, undergoes complete oxidation with solution of potassium permanganate acidified with sulfuric acid and gives only three (3) organic products A, B and C. For each of the products A, B and C the following are given below: Union A With an alkaline solution of iodine, it gives a yellow precipitate. Compound B It is volatile and is therefore widely used as a solvent in dyes. Reduction of compound B, under the appropriate conditions,...

Road map: A, B, and C are cyclic alkyl halides with a molecular formula of C6H11Br. Compound B reacts with Na+ - OCH3 in DMSO at room temperature to give the corresponding ether D. Compound C reacts with Na+ - OCH3 in DMSO to give a different ether E and cyclic trisubstituted alkene F. Compound B reacts much faster with Na+ -OCH3 in DMSO than compound C. Compound A does not give an ether when reacted with Na+ -OCH3 in...

Reaction of compound A, formula C_8H_14O, with the Wittig reagent CH_2=P(C_6H_5)_3 produces compound B, C_9H_16. Treatment of compound A with LiAlH_4 yields two diastereomeric products C and D, both C_8H_16O, in unequal yields. Heating either C or D with concentrated sulfuric acid produces compound E, with the formula C_8H_14. Ozonolysis of E produces a keto aldehyde. Oxidation of this keto aldehyde with chromic acid produces: Identify compounds A through E. Pay particular attention to the stereochemistry.
