Which of the following reactions is an example of nucleophilic substitution reaction?

RX + KOH → ROH + KX

2RX + 2Na → R- R

RX + H₂ → RH + HX

RX + Mg → RMgX

Solution

RX + KOH → ROH + KX

Nucleophilic substitution reactions involve substitution (replacement) of a group or atom by a nucleophile.
KOH → K⁺ + OH-
RX + OH^- → R - OH + KX

Nucleophiles are either negative charge or a lone pair of electrons bearing species, OH^- etc.
