Carbylamine Test

Q.

Is ${\mathrm{NH}}_2$ an amine?

Q. Draw all possible functional isomers of C2H4O.

Q. How to draw the structure for compounds?

Q. ASSERTION: 2-bromo-2 methyl bu†an e + (CH3)3CO-(base tertiary butoxide) =? major product obtained in the reaction is less substituted alkene(2-methyl but-1-ene), not more substituted alkene(2-methyl but-2-ene). REASON : The dehydroha\log enation of an alkyl halide by a base like C2H5ONa gives more substituted olfine(as per Saytzeffs rule), however dehydroha\log enation with a bulky base like tertiary butoxide gives a less substituted olefine as the major product.

Q. Structre of ${}^{\prime }{A}^{\prime }$ and type of isomerism in the given reaction are respectively.
