Question

$\xrightarrow { \mathrm { NaBr } , \mathrm { H } _ { 2 } \mathrm { SO } _ { 4 } }$X

Identify X and the mechanism of the reaction

• A. CH3 – CH2 – CH2 – CH2 – Br & SN1
• B. CH3 – CH2 – CH2 – CH2 – Br &N2
• C. & SN1
• D. & SN2

Answer 1

Answer: (B)

CH3 – CH2 – CH2 – CH2 – Br &N2

Answer 2

$\text{C}\text{H}_{3}\text{ - C}\text{H}_{2}\text{ - C}\text{H}_{2}\text{ - C}\text{H}_{2}\text{ - OH }\underset{S_{N}2}{\overset{\quad\text{NaBr,}H_{2}SO_{4}\quad}{\rightarrow}}\text{ C}\text{H}_{3}\text{ - C}\text{H}_{2}\text{ - C}\text{H}_{2}\text{ - C}\text{H}_{2}\text{ - Br}$

unbranched 1º alcohol give SN2 reaction with HX.
