Which of the following compounds is not formed when a mixture of methyl bromine and ethyl bromine is treated with sodium metal in the presence of dry

Correct Answer - A `CH_(3)-overset(-)CH_(2)` is less stable than `overset(-)CH_(3)" as the "CH_(3-)` group exert +I effect `CH_(3)-CH_(2)` radical is more stable than `CH_(3)`, this is due to `sigma-p` conjugation, also...
