which has more priority in nomenclature secondary tertiary or primary carbon
Answers
Answer:
Organic chemists, with carbon chemistry as their subject, have developed all kinds of shorthand phrases to describe structures and phenomena that might otherwise take a sentence of two to explain. Here’s today’s example: the terminology of carbon-containing functional groups: primary, secondary, tertiary, quaternary.
Primary carbons, are carbons attached to one other carbon. (Hydrogens – although usually 3 in number in this case – are ignored in this terminology, as we shall see).
Secondary carbons are attached to two other carbons.
Tertiary carbons are attached to three other carbons.
Finally, quaternary carbons are attached to four other carbons.
You can’t go higher than that. To have five substitutents, you’d need 10 electrons around carbon, a clear violation of the octet rule. When people do write 5 covalent bonds around carbon, it’s a mistake. (In the trade, these are often called Texas carbons – 1) because it resembles a star, 2) because everything is bigger in Texas, and 3) because the only man who can put five bonds on carbon is also known as Walker, Texas Ranger.)

We use the same terminology for carbocations. A primary carbocation is attached to one other carbon, a secondary to two, and a tertiary to three. You can’t have a quaternary carbocation without violating the octet rule either (you’d need an extra empty p orbital for that, bringing the total to 5).

Alcohols also follow the primary/secondary/tertiary nomenclature. The rule for alcohols is that they are named according to the number of carbons attached to the carbon bearing the hydroxyl group: in other words, whether the hydroxyl bound to a primary, secondary, or tertiary carbon. You can’t have a quaternary alcohol – again, that would involve breaking the octet rule. [A bit of non-essential nomenclature: the carbon attached to the OH is sometimes referred to as the “carbinol” carbon].
