What is Hypovalent species or compounds ?

The compounds or ions which doesn't follow octet rule inspite of that contains less than eight electrons and also stable called Hypovalent species.

For examples BeF2,BF3, CH4+, NF2+, B2H6, Be2Cl4 etc

What is Hypervalent species or compounds?

The compounds or ions which doesn't follow octet rule inspire of that contains more than eight electrons and also stable called Hypervalent species.

For examples XeFe2(10e), XeFe4(12e), SF4(10e), SFe6(12e), IFe7(14e), I2Cl6(10e), TeF5(12e) etc

Hypervalent species may act as Lewis acid but not always.
