How To Recognize Primary, Secondary, Tertiary (and sometimes Quaternary) Hydrocarbons, Carbocations, Alkyl Halides, Alcohols, Amines, and Amides. Primary (1°), secondary (2°), tertiary (3°) and quaternary (4°) alkyl carbons are defined according to the number of carbonsdirectly attachedto ...
Which one of the following is obtained if two hydrogens of ammonia replace with alkyl groups? (a) primary amine (b) secondary amine (c) tertiary amine (d) amide Is (CH_3)_2CHNH_2 a secondary amine? Give a reason for your answer. ...
It is basic in nature due to the presence of lone pair of electrons on the nitrogen atom of the amine. It is classified into different groups on the basis of the alkyl substitution. Primary amine Secondary amine Tertiary amine Quaternary amine...
Identification of Primary, Secondary, and Tertiary Alcohols: An Experiment in Spectrophotometry, Organic Chemistry, and Analytical Chemistry A simple method is presented that enables students to distinguish in a few minutes between primary, secondary and tertiary alkyl alcohols. This method is b... Lee...
Primary, secondary and tertiary amides, lactams and imides are readily alkylated on the carbonyl oxygen by trialkyloxonium tetrafluoroborates, dialkyl sulfates and alkyl halides to give alkoxymethylene iminium salts (5) <56CB2060, 61AG493, 63CB1350>, and see the comprehensive reviews by Kantlehner...
tertiary alkyl halide C primary alkyl halide D None of these Solution Verified by Toppr 2-bromopropane CH3−CH(Br)−CH3 is a secondary alkyl halide. In secondary alkyl halide, the halogen atom is attached to a C atom which itself is attached to two other C atoms and one H atom. Was...

aThe exchange reaction between tertiary Mannich bases (I) and primary alkylamines has been shown to give the monosubstituted secondary Mannich bases (II), and the nonavailability of the latter by the normal Mannich reaction is accounted for by their instability to base, including the basic group ...
