A. tert-Butyl bromide
B. Isobutyl bromide
C. 2-Methylbutane
D. None of these

Answer 1

Correct Answer - C
`2^(@)` or `3^(@)` alcohols in the presence of conc. `H_(2)SO_(4)` readily undergo elimination.
`CH_(3)-overset(CH_(3))overset("| ")underset(CH_(3))underset("| ")("C ")-OH overset(KBr//H_(2)SO_(4)(conc.))underset(-H_(2)O)rarr underset("2-Methylbutene")(CH_(3)-overset(CH_(3))overset("| ")("C ")=CH_(2))`
