Question

Which of the following reaction will not give ether as a major product ?
A. `CH_(3)CH_(2)Cl+Ag_(2)O`(dry)
B. `(CH_(3))_(3)C Cl+CH_(3)CH_(2)O^(-)Na^(+)rarr`
C.
D. `CH_(3)Cl+overset(+)(N)a overset(-)O-overset(CH_(3))overset("| ")underset(CH_(3))underset("| ")("C ")-CH_(3)rarr`

Answer 1

Correct Answer - B
Ether formation using alkoxide with alkyl halide is a `S_(N^(2))` reaction and is best for `1^(@) RX. 2^(@)` and `3^(@)RX` readily undergo elimination in the presence of a strong base to form alkenes
`CH_(3)-overset(CH_(3))overset("| ")underset(CH_(3))underset("| ")("C ")-Cl+CH_(3)CH_(2)ONa rarr CH_(3)-underset(CH_(3))underset("| ")("C ")=CH_(2)+NaCl+CH_(3)CH_(2)OH`
