Identify the product in the reaction P h C ≡ C M e → H 3 O + , H g 2 + ?

Due to higher stability of this cation [ P h - C ⊕ = C M e ] than methyl cation, the - O H ⊕ will attack on the benzylic cation. Hence P h C O C H 2 C H 3 would be the major product.

Identify the product in the reaction $P h C \equiv C M e \overset{H_{3} O^{+}, H g^{2 +} ?}{\to}$

Options:

Answer:

Solution:

Due to higher stability of this cation $[P h - \overset{\oplus}{C} = C M e]$ than methyl cation, the $- O \overset{\oplus}{H}$ will attack on the benzylic cation.
Hence $P h C O C H_{2} C H_{3}$ would be the major product.
