    Not possible. because RMgX is base and internal alkyne doesn't have acidic H. Only terminal alkyl can react with RMgX due to acidic H

    why rmgx is a nucleophile

    eduncle-logo-app

    Because it contains a carbon centre more or less directly bound to an electropositive metal centre.

    Not Possible as in RMgX R is nucleophile and triple bond is also nucleophile
