WebEmpirical formula mass of compound A. Molecular mass of compound A =86. Empirical formulamass of compound A= 5 x 12 +1 x 10+1 x 16= 60 +10+ 16=86. 86. n=1. Molecular formula ofthe compound A = 1 (CsH100)=C,H100. As the compound A forms addition compound with NaHSO, therefore it must be either an aldehyde or ketone.

MCQs CARBONYL COMPOUNDS

WebAldehydes and Ketones are often called as methanoyl or formyl group. The carbon atom of this group has 2 remaining bonds that might be occupied by aryl or alkyl or substituents. If neither of these substituents is hydrogen, the compound is a Ketone. If at least one is hydrogen, the compound is an Aldehyde. Occurrence of Ketones and Aldehydes WebAn acid-induced rearrangement of oximes to give amides. This reaction is related to the Hofmann and Schmidt Reactions and the Curtius Rearrangement, in that an electropositive nitrogen is formed that initiates an alkyl migration.

WebAlcohol Reactions. The functional group of the alcohols is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond. The electronegativity of oxygen is substantially greater than that of carbon and hydrogen. Consequently, the covalent bonds of this functional group are ...

WebAldehydes and ketones react with water to give 1,1-geminal diols known as hydrates. In general, hydrates are not stable enough to be isolated as the equilibrium shifts back to starting materials (due to Le Chatelier's principle). However, hydrates are the reactive species in the aqueous oxidation of aldehydes to acids.
