Identify the three alkynes A, B `(CH_(10)H_(18))`, and C `(C_(10)H_(16))` which give the following reactions.

Text Solution

Verified by Experts

i. Since alkyne (A) reacts with Grigand reagent, so it must have a terminal acidic H atom.
Structure of (A) is:

ii. Since alkyne (B) has no reaction with Grignard reagent, it should be internal and symmetrical alkyne, as evident from the oxidative cleavage reaction with hot alkaline `KMnO_4`.
Structure of B is:

iii. DU in `(D)=((2xx10+2)-20)/(2)=1^@`
C and D must be by cyclic ring of 10 atoms.
Structure of C:
