Amines are well known to be stronges bases and nucleophiles than alkenes. Why do enamines, such as 1-dimethylaminocyclipentene, reacts with elecrophiles at a double bond carbon rather than at nitrogen?

Alkenes are more reactive than alkynes towards electrophillic addition reaction, yet vinyl acetylene reacts with 1 mol of HBr at triple bond. Explain why.

Statement 1 : Xenon fluorides are well known and stable but the corresponding chlorides have not been reported. Statement 2: Xe-F bond is more strong than Xe-Cl bond and F_2 molecule has low bond dissociation energy than that of Cl_2 molecule.

(A) Xenon fluorides are well known and stable but the corresponding chlorides have not been reported. (R) Xe-F bond is more strong than Xe-Cl bond and F_2 molecule has low bond dissociation energy than that of Cl_2 molecule.

Assertion : Xenon fluorides are well known and stable but the corresponding chlorides have not been reported. Reason : Xe-F bond is more strong than Xe-Cl bond and F_2 molecule has low bond dissociation energy than that of Cl_2 molecule.

Ester gives nucleophilic addition reaction followed by elimination reaction with carbon nucleopile. When carbon nucleophile is of an ester then the reaction is known as Claisen condensation reaction. This reaction is also carried out between ester and a ketone. A suC Cessful Claisen condensation requires an ester with two alpha- hydrogens and an equivalent amount of base rather than a catalytic amount of base. Intramolecular Claisen condensation given diester is known as :
