According to carbinol system tert butyl alcohol is named as,
Options
- AMethyl carbinol
- BEthyl carbinol
- CPropyl carbinol
- DTrimethyl carbinol
Correct answer
A. Methyl carbinol
Step-by-step solution
In the carbinol system, alcohols are named as derivatives of methanol by replacing hydrogen atoms on the methyl group with substituents. Tert-butyl alcohol has the formula (CH₃)₃C -- OH , where the carbinol carbon is bonded to three methyl groups. This corresponds to trimethyl carbinol. The alternatives correspond to different structures: methyl carbinol ( CH₃CH₂OH ), ethyl carbinol ( CH₃CH₂CH₂OH ), and propyl carbinol ( CH₃CH₂CH₂CH₂OH ). The correct carbinol system name is therefore trimethyl carbinol.
