Which of the following statement(s) is/are correct?a)Guanidine is mor...
Explanation:
Statement a: Guanidine is more basic than pyridine because the conjugate acid of guanidine has three equal contributing resonating structures.
Guanidine (HNC(NH2)2) is a stronger base than pyridine (C5H5N) because the conjugate acid of guanidine can be stabilized by resonance. The three nitrogen atoms in guanidine can donate their lone pair of electrons to the hydrogen atom, resulting in three equal contributing resonating structures. This delocalization of positive charge stabilizes the conjugate acid, making guanidine a stronger base than pyridine.
Statement b: Diethylamine is a stronger base than triethylamine in aqueous medium.
Diethylamine (C2H5)2NH is a stronger base than triethylamine (C2H5)3N in aqueous medium. When these amines are dissolved in water, they undergo protonation by accepting a proton from water. The electron-donating ethyl groups in diethylamine increase the electron density on the nitrogen atom, making it more basic and more likely to accept a proton. Therefore, diethylamine is a stronger base than triethylamine in aqueous medium.
Statement c: The ortho-methyl aniline is a weaker base than para-methyl aniline.
Ortho-methyl aniline and para-methyl aniline are both substituted anilines, where a methyl group is attached to the benzene ring. The position of the methyl group affects the basicity of the amine. In ortho-methyl aniline, the methyl group is attached to the ortho position (adjacent to the amino group), while in para-methyl aniline, the methyl group is attached to the para position (opposite to the amino group).
The ortho-methyl aniline is a weaker base than para-methyl aniline because the ortho position is sterically hindered by the presence of the methyl group. This steric hindrance reduces the availability of the lone pair of electrons on the nitrogen atom for protonation, making ortho-methyl aniline a weaker base than para-methyl aniline.
Statement d: 2,4,6-Trinitro-N,N-dimethyl aniline is a stronger base than 2,4,6-Trinitroaniline.
2,4,6-Trinitro-N,N-dimethyl aniline is a stronger base than 2,4,6-Trinitroaniline. The presence of the dimethylamino group (-N(CH3)2) in 2,4,6-Trinitro-N,N-dimethyl aniline increases the electron density on the nitrogen atom, making it more basic. This increased electron density makes 2,4,6-Trinitro-N,N-dimethyl aniline a stronger base than 2,4,6-Trinitroaniline.
In summary, the correct statements are a) Guanidine is more basic than pyridine because the conjugate acid of guanidine has three equal contributing resonating structures. b) Diethylamine is a stronger base than triethylamine in aqueous medium. d) 2,4,6-Trinitro-N,N-dimethyl aniline is a stronger base than 2,4,6-Tr

Statement d: 2,4,6-Trinitro-N,N-dimethyl aniline is a stronger base than 2,4,6-Trinitroaniline.
2,4,6-Trinitro-N,N-dimethyl aniline is a stronger base than 2,4,6-Trinitroaniline. The presence of the dimethylamino group (-N(CH3)2) in 2,4,6-Trinitro-N,N-dimethyl aniline increases the electron density on the nitrogen atom, making it more basic. This increased electron density makes 2,4,6-Trinitro-N,N-dimethyl aniline a stronger base than 2,4,6-Trinitroaniline.

1. Guanidine is a stronger base than pyridine. The increased basicity can be explained by drawing the resonance structures of the protonated guanidine.
2. Dimethylamine is more basic than trimethylamine in aqueous medium. This is due to the fact that steric hindrance created by alkyl groups affect the solvation so badly that the tertiary amines are usually the least basic among the three classes. Due to the presence of 3 alkyl groups, there is a lot of steric hindrance and therefore, it is difficult for nitrogen to form H-bonds with the hydrogen atom of water for proper solvation.
3. Ortho one is more basic due to the inductive effect of the methyl group.
4. 2,4,6-Trinitro-N,N-dimethyl aniline is a stronger base than 2,4,6-Trinitroaniline because the steric repulsion of -N(CH3)2 goes out of the plane of the ring.
