Which of the following behaves both as a nucleophile and as an electrophile ?
A.
$$C{H_3}C \equiv N$$
B.
$$C{H_3}OH$$
C.
$$C{H_2} = CHC{H_3}$$
D.
$$C{H_3}N{H_2}$$
Answer :
$$C{H_3}C \equiv N$$
Solution :
Due to the presence of a lone pair of electrons on $$N,C{H_3}C \equiv N:$$ acts as a nucleophile. Further due to greater electronegativity of $$N$$ than $$C,$$ the $$C$$ atom of $$ - C \equiv N$$ carries a positive charge and hence behaves as an electrophile.
