Question

$C{H}_3-\stackrel{C{H}_3}{\stackrel{|}{\underset{C{H}_3}{\underset{|}{C}}}}-C{H}_{2}Br\stackrel{C_2{H}_{5}OH}{\to }$ products.
Products can be:

• A. $C{H}_3-\stackrel{C{H}_3}{\stackrel{|}{\underset{O{C}_2{H}_5}{\underset{|}{C}}}}-C{H}_{2}C{H}_3$(Major)
• B. $C{H}_3-\stackrel{C{H}_3}{\stackrel{|}{C}}=C{H}_{2}C{H}_3$ (Minor)
• C. both are correct
• D. none of these

Answer 1

Answer: (A)

$C{H}_3-\stackrel{C{H}_3}{\stackrel{|}{\underset{O{C}_2{H}_5}{\underset{|}{C}}}}-C{H}_{2}C{H}_3$(Major)

A primary alkyl halide will prefer a substitution reaction, a tertiary halide prefer an elimination reaction.
