Replacing one hydrogen from NH3, by alkyl group will result in the formation of
- aldehyde
- ketone
- amine
- ester
The Correct Option is C
Solution and Explanation
When one hydrogen atom in \(NH_3 (ammonia) \)is replaced by an alkyl group, it forms an amine. Amines are compounds derived from ammonia with one or more hydrogen atoms replaced by alkyl or aryl groups.
Top Questions on Amines
Amines have a lone pair of electrons on the nitrogen atom, due to which they behave as Lewis bases. Greater the value of \( K_b \) or smaller the value of \( pK_b \), stronger is the base. Amines are more basic than alcohols, ethers, esters, etc. The basic character of aliphatic amines should increase with the increase of alkyl substitution. However, it does not occur in a regular manner, as a secondary aliphatic amine is unexpectedly more basic than a tertiary amine in aqueous solutions. Aromatic amines are weaker bases than ammonia and aliphatic amines. Electron-releasing groups such as \( -CH_3 \), \( -NH_2 \), etc., increase the basicity, while electron-withdrawing substituents such as \( -NO_2 \), \( -CN \), halogens, etc., decrease the basicity of amines. The effect of these substituents is more pronounced at the para-position than at the meta-position.
