Front

Define oxidation and reduction in terms of electron transfer.

Back

Oxidation is the loss of electrons; reduction is the gain of electrons.

Front

What is the general trend of electronegativity in the periodic table?

Back

Electronegativity increases across a period and decreases down a group.

Front

What is the difference between haloalkanes and haloarenes?

Back

Haloalkanes have halogens attached to saturated carbon atoms, while haloarenes have halogens attached to aromatic rings.

Front

What is the significance of the octet rule in atomic structure?

Back

The octet rule is significant because it explains the stability of atoms and the formation of chemical bonds.
