Predict the major product obtained when t-butyl bromide reacts with sodium methoxide. Also, give its IUPAC name.

OR


(a) Show the chemical reaction with bond movements and arrows for the nucleophilic attack of water on carbocation in acid catalysed hydration of alkenes.


(b) Give IUPAC name for the following:



(CH3)3Br + CH3ONa → (CH3)2-C=CH2 + NaBr + CH3OH


(t-butyl bromide) (2-methylpropene)


When secondary or tertiary alkyl halide is used elimination reacton takes place instead of substitution.


OR


(a) Nucleophilic attack of water on carbocation in acid catalysed hydration of alkenes is as follows


Step 1: Protonation of alkene to form carbocation by electrophilic attack of H3O+.


H2O + H+→ H3O+



Step 2: Nucleophilic attack of water on carbocation.


Step 3: Deprotonation to form an alcohol.



(b) IUPAC name for the given compound is 2,6-dimethylphenol or 2,6-Xylenol.
