In t-butyl alcohol, tertiary carbon is bonded to:
Correct answer: D. No hydrogen atom
- A. Two hydrogen atoms
- B. Three hydrogen atoms
- C. One hydrogen atom
- D. No hydrogen atom
Explanation
The central (tertiary) carbon atom in t-butyl alcohol is bonded to three methyl groups (-CH3) and a hydroxyl group (-OH). This configuration characterizes the t-butyl group, giving the molecule its name. The presence of three carbon substituents and one hydroxyl group means there are no hydrogen atoms bonded directly to this tertiary carbon. Options A, B, and C are incorrect because they suggest the presence of hydrogen atoms bonded to the tertiary carbon, which is not the case in t-butyl alcohol.

About Alkanes
Alkanes are saturated hydrocarbons containing only carbon-carbon and carbon-hydrogen single bonds, with the general formula CnH2n+2 for open chains. Their structure, isomerism, IUPAC nomenclature, physical properties, combustion, free-radical halogenation and conformations are covered, including the difference between substitution in alkanes and addition in unsaturated hydrocarbons.
