Question

Which is the main product of the given reaction?

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

The elimination reaction of a substrate with a sterically unhindered/​less bulky base​ generally gives the most stable alkene which is more substituted, i.e. normal Saytzeff product, but sterically hindered bulky base leads to a terminal or less substituted alkene, i.e. Hofmann product.
Bulky base $(t-Bu{O}^{-}{K}^{+})$ is present thus it will give Hofmann product as a major product.
