Front

Define haloalkanes.

Back

Haloalkanes are alkanes in which one or more hydrogen atoms are replaced by halogen atoms.

Front

What is the general formula for haloalkanes?

Back

The general formula for haloalkanes is CnH2n+1X, where X is a halogen.

Front

What is the difference between nucleophiles and electrophiles?

Back

Nucleophiles are electron-rich species that donate electrons, while electrophiles are electron-deficient species that accept electrons.

Front

What is the significance of the leaving group in a nucleophilic substitution reaction?

Back

The leaving group is important because it affects the reaction rate and mechanism; better leaving groups facilitate faster reactions.
