Q.Name t-butyl alcohol using carbinol system of nomenclature.

Monohydric alcohols are named by three parallel systems. Common/trivial names add the word 'alcohol' after the alkyl group's own name (methyl alcohol, ethyl alcohol), with branching prefixes like normal-, iso-, sec- and tert- distinguishing isomeric alkyl groups. The carbinol system treats every alcohol as a substituted derivative of methyl alcohol (renamed 'carbinol'), naming the alkyl group(s) attached to the carbinol carbon as a prefix (e.g. ethanol as 'methyl carbinol', tert-butyl alcohol as 'trimethyl carbinol'). The IUPAC system names alcohols as alkanols: the parent hydrocarbon's terminal '-e' becomes '-ol' (ethane to ethanol), with the -OH-bearing carbon given the lowest possible locant; polyhydric alcohols instead RETAIN the parent's '-e' and add a di-/tri- multiplying prefix before '-ol' (et …
