How many types of carbon atoms (primary, secondary, tertiary, quaternary) are present in the structu — Hydrocarbons Chemistry Question

💡 Solution & Explanation

The structure of 2,2,3-trimethylpentane is $CH_3-C(CH_3)_2-CH(CH_3)-CH_2-CH_3$. It contains primary ($1^{\circ}$) carbons (the five methyl groups), secondary ($2^{\circ}$) carbon (the $CH_2$ group), tertiary ($3^{\circ}$) carbon (the $CH$ group), and a quaternary ($4^{\circ}$) carbon (the $C$ atom bonded to four other carbons). Therefore, all four types of carbon atoms are present.
