Types of Carbon based on attachment

Primary, Secondary and Tertiary Carbon Atom

Primary carbon atom

If a carbon atom attached to functional group is directly attached to only one carbon atom, then it is said to be a "Primary carbon atom" or "1^o C-atom".

SECONDARY CARBON ATOM

If a carbon attached to functional group is directly attached to the two C-atoms, then it is said to be "Secondary carbon atom" or 2^o C-atom".

Tertiary Carbon Atom

If the carbon atom that is attached to a functional group is directly attached to three C-atoms, then it is said to be a "Tertiary carbon atom" or "3^o C-atom".
