Q -

What are :

1) Primary Carbons / Hydrogens

2) Secondary Carbons / Hydrogens

3) Tertiary Carbons/ Hydrogen

4) Quaternary Carbons / Hydrogens​

Answer 1

Explanation:

• A primary carbon is a carbon atom which is bound to only one other carbon atom. It is thus at the end of a carbon chain. In case of an alkane, three hydrogen atoms are bound to a primary carbon (see propane in the figure on the right).
• A secondary carbon is a carbon atom bound to two other carbon atoms. For this reason, secondary carbon atoms are found in all hydrocarbons having at least three carbon atoms. In unbranched alkanes, the inner carbon atoms are always secondary carbon atoms (see figure). primary carbon
• A tertiary carbon atom is a carbon atom bound to three other carbon atoms. For this reason, tertiary carbon atoms are found only in hydrocarbons containing at least four carbon atoms. Tertiary carbon atoms can occur, for example, in branched alkanes, but not in linear alkanes.
